Too many pens and their refills are disposable by design. Similar to printer ink cartridges, pen companies want you to buy into their format so they can keep selling you replacement pens or refills repeatedly. It's good for their business, but it's bad for the planet and stifles creativity.

"It is brilliant: Beautiful, the perfect weight, a range of nibs, satiny ink. The drawing (almost) does itself."
David Downton

As a product designer and craftsman who loves using a variety of pens to create illustrations and designs, I had this very problem! Pens would sit in my drawer for years, either patiently waiting for that very specific refill, or I was just loath to dispose of an otherwise fully functional pen that had run out of ink.

Having designed and handmade calligraphy and fountain pens for creative folks across the world full-time for over 6 years, I decided it was time to apply my knowledge to the pen I used most of all and one of the biggest culprits when it came to its disposable nature: the fineliner.

    Included in the box:

    • The Lumos Pro Single or Duo in your choice of colour – grippy matte black, midnight or satin-finished Sage, Lilac, Ivy, Raspberry or Blush
    • The Lumos Full Creative Tip Set
    • 3ml Deep Black Ink sample
    • Ink Reservoir (Lumos Pro Single x1, Lumos Pro Duo x2)

    Specifications:

    Lumos Pro Single/Duo

    • Length capped – 155mm
    • Length uncapped – 145mm
    • Pen barrel diameter – 10mm
    • Weight – 20g
    • Made from Anodised Aluminium

    The Lumos Full Creative Tip set contains 11 tips:

    • Fineliner: 0.1, 0.2, 0.3, 0.5, 0.8, 1.0
    • Felt-Tip: Chisel, bullet & brush
    • Writing: 0.3, 0.5

    Full FAQs and a video guide to getting started with your Lumos can be found here.

    How many lids does the Lumos Duo come with?

    The Lumos Duo is designed so that one half of the pen acts as the lid for the other. The lid covers one tip, while the other should be screwed into the middle of the pen for storage. This keeps things compact, balanced, and secure – no juggling extra lids.

    Prefer both ends capped? You can add a second lid to your pen here.

    What ink can I use?

    The Lumos is compatible with dye-based Fountain Pen Inks, so long as they don’t contain particles (such as shimmer inks) or binders (like acrylic or shellac).

    Exception to the rule? We sell a splendid waterproof pigment ink: No.60 Pigment Black.

    What are the differences between the Duo and the Single Lumos?

    The Single Lumos has one tip and one ink reservoir, which is double the Duo's reservoir size.

    The Duo Lumos allows you to have two different pens in one body, allowing you to easily change between nibs and ink colours on either side.

    Can I purchase replacement tips and reservoirs for my Lumos?

    Yes! Everything you need for your Lumos is listed below:

    Amazing pens - loving the Lumos Pro pens and accessories

    This is the second Lumos Pro I have bought, the first being in the Sage colour. This time in the beautiful Rose Gold.

    Again, I had it engraved with my name and job title. 

    Loving the ink colour No.7. Mallard. For someone who mainly writes in black this is a lovely change. 

    Bought some extra accessories (nibs and reservoirs) also, the lids for the pens in matching colours as I bought the single tip pens and they finish them off nicely. 

    Luxurious feel when writing, I'm finding excuses to write things down. 

    So thankful for coming across an ad on Facebook to open my world to Tom's Studio. 

    Loving my new pens and don't think I'll ever go back to plastic

    From Lada to Rolls Royce

    I love the Lumos Pro. I've been using fineliners for years as much for convenience as anything. But I feel like I have upgraded from a Lada to a Rolls Royce with the Lumos Pro. It's beautifully weighty in my hand. The Matt finish is tactile and feels secure in my hand and the ink flow, it's so, so smooth. The whole thing is just superb.

    Best pen EVER

    I’ve had the Lumos Pro Single tip for only a day and I’m literally obsessed beyond belief. The pen feels nicely heavy in the hand, but not overly so, just right to feel expensive. The color options available? I want all of them! It writes so smooth it’s not even funny. This probably the only pen I’m ever going to own now. Price point well worth the quality.

    Lumos Splash

    I bought my Lumos from a bricks and mortar store in my city. It writes BEAUTIFULLY. I bought two Tom's Studio inks to go with it, Deep Black and Cassis which are gorgeous. I particularly like how I get a muted version of the Cassis in the Lumos and the full saturated colour in my vintage fountain pen. Now I love my Lumos but I have concerns (and I am being finicky here) I noticed some chips in the finish on the end of the pen. This is disappointing given the price of the pen. It looks like a manufacturing flaw. I'm a bit worried that the chips may worsen tiny as they are and affect the finish of the pen. The pen finish, well this one seems to have missed the quality control. I have tried the chisel tip 0.2 fineliner, 0.5 writing tip and really pleased with all of them. As a left hander who writes with a broad oblique fountain pen nib, the chisel tip is a particular favourite.

    Great pen, Not Quite My Tempo!

    Is it a refillable fineliner ? YES
    Does it lay down a vibrant Black line like it's disposable plastic competition? Not quite

    Gives a Dark visible grey regardless of ink Toms Studio No.1, No.60 Waterproof and even Platinum Carbon Black even with fresh reservoir and tips... lines require repeat layering and come to the conclusion it's how the pen writes.

    Positives- Redeeming Qualities

    GREAT lines despite everything , truly an amazing job there no drying out yet or skipping.

    Gladly use this over any disposable fineliner due to my eco conscious nature.

    I own about 5 lumps duos accumulated over 3 or 4 years. The build quality has always been very good, but the last couple pens I've got have been exceptional, product of continued product development no doubt. Thanks Tom and team!

    Incredible!

    I wanted to just thank you for such a beautiful pen! I got a lumos and I've been running an experiment on how many pages I can write on one full reservoir, and so far I'm up to 21 pages with no sign of running out. What an incredible product. The balance and weight of the pen is perfect. Thanks again!

    the perfect pen :)

    this pen is the perfect weight for me out of the other pens i've tried from here (all lovely btw). the color is beautiful and even, the components all come apart and go back together smoothly, and the ridges on the cap offer the perfect amount of friction for me to unscrew the cap without assistance or joints dislocating (i have poor grip strength & my joints partially dislocate a lot due to my disability, for context!). i love pens from here so much- between the unboxing and watching the capillary action in the tube, this is my "forever" pen brand :)) <3

    Amazing customer service

    I had my double lumos for only three weeks before somehow my center part became stripped. I reached out to Tom’s Studio without much thought they’d be able to help but I was so wrong. In less than a day I had a reply from a lovely kind person named Jade and after sending video proof of my broken pen, another amazingly kind person, Laura, took over. And now, less than a week later, I have received an entire new body for my lumos. From going in expecting nothing to receiving the entire new body of a pen I am blown away. I was able to switch over the pen guts and pen cap to my new body and now I am back to using it happily again.

    Thank you guys so much. I am so eternally grateful to no longer have to tape my lumos in the center so it doesn’t fall apart.

    Gorgeus pen! 💚

    After I fall in love in my Wren, I finally desided to invest in the light green Duo Lumos!
    Both are very comfortable - the right size for me, and easy to write with - I can write over 2 - 3 hours without any pain in my hand!
    The tips are great idea and everything is very easy
    to clean.
    The customer service is beyond perfect and I already reccomend my pens to friends.
    I love the eco idea - we need to consume less because our planet is our home 🌏🌳!
    Thank you Tom, Jade, Rachel and Team!

    Perfect mix of creative and every day use

    I bought myself a Lumos Pro after receiving a Wren from my daughter, which I love using.
    I have always loved using really nice pens but don’t like the waste of throwing a pen away when the ink has gone.
    I keep the Wren in my bag, for daily use but wanted something that I could practise calligraphy with. Seeing the 11 tips that come with the Lumos Pro, including a brush tip, I knew that was the choice for me.
    I chose the lilac, to match my Wren and 5 sample inks to see how I got on.
    I received my Lumos Pro not long after and it was beautifully packaged. Even my dog, Poppy, wanted to get in on the unboxing action; she clearly recognises excellent craftsmanship!
    The pen is beautifully weighted, was easy to fill and feels great on paper. I’m happy that I will be able to buy replacement tips and reservoirs, so no more disposables for me!
    Finding Tom’s Studio was a stroke of luck

    Good pen with subpar tips

    I really like the pen and thought it was easy enough to put together. I was very excited to find a refillable pen you can use a brush tip with. However, the tips aren't great. They only spread a very thin layer of ink. When I use black, I need to apply 3 layers for it to actually look black. Maybe not so bad if you're using different colors and the exact shade you get isn't such a big deal. But I need my black linework to actually be black, and it's a whole lot of work to make that happen with these tips. Such a shame because I love the pen itself.

    Wow!! So in love with this pen!

    Just received my Lumos Duo and I am in love. The attention to packaging makes it such a special treat just to open. And then THE PEN. The size and weight feel beautiful in my hand. I put in the brush tip and loaded with the No.60 black ink with not a bit of trouble or extra ink anywhere. It writes beautifully! And I love the versatility of this brush tip (as seen in the picture). I did purchase the leather finger grip which I recommend, as the pen itself is smooth and slippery. I cannot wait to spend hours exploring all the options this pen has to offer!

    A renewed joy of writing

    The Lumos Duo Pro (and Mini) is wonderful to write with.
    It feels right and has a nice weight to it. It also feels good because you're not throwing away plastic pens all the time. Yeah!!
    To write in two different colours with one refillable pen is truly awesome, switching between colours is easy.
    And I absolutely love the Sage green colour of my Lumos Duo Pro. And the Blush Mini is pretty and feminine.
    I haven't tried all the pen tips yet, but I'll enjoy those as much as I enjoy the fineliner tips, no doubt.
    The packaging was good too! And the tea was a lovely treat. 💖

    Sustainable and great

    I have been using the Lumos Pro for several weeks now. I draw a lot with it and am absolutely thrilled. In the past, I had to throw away so many pens, which I really didn’t like. Then I came across Tom’s Studio and ordered the Lumos Pro. It is the best pen for what I want to do, and the fact that you can replace the nibs and refill the ink is simply fantastic. The nibs glide so smoothly over the paper, and the feel of the pen is just amazing. I am delighted to finally be able to draw sustainably. Thank you very much for that.....Nicole

    The pen of my dreams

    I’m so pleased I finally invested in the Lumos pro. All my designs are with fine liners and I was getting conscious of using single use pens, but the Lumos pro is the answer. It’s excellent quality and a good weight to draw or write with. I couldn’t recommend it more.

    Smoooooooooth

    I love it, writing with my Diamine Poppy Red Ink. Such a smooth writer on paper. Weighted just right, and lots of nib options.

    Beautiful pen!

    I’ve been thinking about buying a Lumos for a long while now and I’m so glad I finally did! It has a nice weight and the collection of nibs is versatile and useful. And the special edition Sunset color is so gorgeous! I adore it.
