The Bic pen is one of the most popular writing instruments in the world, with over 100 billion produced since its inception. While convenient, consistent, and light, the fact that these billions of pens will sit in landfills for thousands of years is a major downside.

That's why I designed the Lumos - Refillable Writing Pen. This pen is built to last and provide as much utility as possible. Here are some of its features:

  • Infinitely refillable: The Lumos writing pen has a reservoir that can be easily refilled just by dipping it in ink. It works by capillary action, which feeds the pen tip and keeps the ink flowing beautifully.
  • Two tip sizes: The refillable pen comes with a fine (approx. 0.3) writing tip.
  • Any ink colour: You're no longer limited to just blue and black. You can refill your pen with any fountain ink colour, including waterproof pigment ink.
  • Smooth tips: The Lumos writing pen comes with an incredible Japanese-made writing tip that provides just the right level of feedback on paper. You can write at any angle, and the tip is incredibly durable, so no matter how hard you press on the paper, it will take it. When the tip does eventually wear out, all that needs replacing is this tiny tip.
  • Drawing the line: Disposable drawing pens are also a problem, but the Lumos pen solves that issue too. With its rounded tip, you can make hairline strokes as well as thicker lines, and the pen has a beautiful feel on the page. Combine it with pigment inks, and you have a professional drawing pen with an extremely durable tip.
  • Endlessly interchangeable: The Lumos Refillable writing pen doesn't limit you to just one tip type. You can easily swap between another 9 different tip styles, including fineliners (0.1, 0.2, 0.3, 0.5, 0.8, 1.0) and felt-tips (2mm chisel, bullet, and brush). You can find the full creative tip set here.

GOOD TO KNOW:

  • Choose between: Super Grippy Matt Black
  • The Lumos - Refillable Writing Pen comes with a 0.3 writing tip. You can buy replacement writing or other tips here in packs of 3 here: Lumos tips. 
  • A reusable cotton core reservoir for each nib, spares available here: Lumos reservoirs. The longer version works in this pen
  • The Lumos Write weighs 20g and is 10mm in diameter 
  • The pen includes a Tom's Studio - Deep Black Ink (not waterproof) 5ml bottle of ink. More colours are available here: Fountain pen ink as well as waterproof pigment inks . Calligraphy Inks are not compatible (find out more in FAQs below).

    Full FAQs can be found here

    What ink can I use?

    - All nibs will work with all but the most experimental fountain pen inks (think shimmer + iridescent). I've tried a LOT and I'm yet to find one that doesn't work well. I'd encourage you to experiment and find the inks that work best for you!

    Pigment Ink for fountain pens can be found here.

    Calligraphy Ink has an acrylic binder which will block the Pen

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

    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.

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

    What's the difference between the Lumos and other refillable technical pens? (E.g. Rotring Isograph and Copic Multiliner).

    Truly fantastic!

    This pen is fantastic to write with. The quality and balance is excellent. On top of that, the ability to easily refil the ink with little to no waste is excellent.

    I'm very picky about my pens -- I LOVE the Lumos!

    I've had many pens over the years. Some I've loved (my ACME rollerball and my Lamy fountain pen especially). However, I have never had the experience of falling in love with a pen until I started using the Lumos Write. (I am not prone to hyperbole by the way).
    It's unusual in its design, and it took me a while to get the hang of it. With some fiddly products I just want to give up. But the Lumos compelled me to get over the hump.
    I love so many things about it, most notably the super-smooth flow of ink and the weight and balance of it in my hand. I thought I was buying a good replacement for cheap pens, but it's so much more than that. I'm doing something I never thought I'd do--using it to replace the Micron 01 I've used for years to draw with. I ordered some Sailor waterproof ink, which works beautifully. In an ideal world, there'd be a nib even finer than the .1, but it's pretty close the Micron. This pen just makes me want to keep drawing.
    The fact that it doesn't have a cap (or a plug in the bottom, depending on how you want to look at this) is a bit odd, but it doesn't have any real implication.
    I loved it so much I immediately bought a duo version as well. I bought it from a Canadian supplier, and the only colour option was green. I didn't realize that the texture would be different, and I found it a bit slippery and not comfortable for drawing. However, I've added a pen grip to correct that problem. I really wish I'd bought it in the matte black like the single lumos, though.
    Judging by reviews, this pen isn't for everyone. But if it does work for you, it's a real love affair. Thank you Tom's Studio!

    Great! But Tactile Sensitivity

    I love this pen. It's a perfect alternative to my other fountain pens. The only issue I have is that it feels like a chalkboard and the screw cap functions in a way that sets off my tactile sensitivities. Because I love this pen so much, I'm able to handle it despite that sensitivity. If it came in different coating options (like the minis) I would purchase another.

    I'm in love

    First thoughts, Mmmm looks a bit too "masculine", but after writing with it, I'm smitten. Not only a smooth writing experience, but my doodling has reached new highs. I'm experimenting with pen and ink drawing. I love it

    Things aren't always Black and White.

    Any ink colour anytime.  The Lumos is designed so that you can refill with any fountain pen ink (and even some pigment inks).  So there are no limits to your colour palette when creating your next masterpiece.

    Make it Yours

    We all have our favourite nib sizes and styles. Customising your Lumos to be your perfect writing, drawing or doodling companion couldn't be easier!

    Watch the how to:

    Tip, Top, Tips

    Japan is where the best technical pens are made.  I was never going to be able to design anything that came close to the precision and decades of perfectionism of a Japanese-made nib.  So I designed the Lumos around them, with 9 sizes and types you are sure to find the ones to perfectly suit your style. 

    Reduce, Reuse, Refill

    It's always seemed crazy to me to have to dispose of an otherwise amazing pen, just because it has run out of ink!  With it's interchangeable ink reservoir the Lumos allows you to easily refill with your ink colour of choice.  You'll also never have to buy another pen again! No more refills, No more waste

    Power Couple

    As a designer, I am always reaching for at least two pens to highlight or add details in different styles to my work.  Different pen styles offer different functions, whether that's accentuating detail in a drawing, changing between line weights, or just doodling for the fun of it I wanted to create a pen that you could use for a variety of tasks and that you could truly customise to the way you work.
