The Lumos Mini has all of the versatility and refillability of its big brother but in a pocket friendly package.
A Mini Pen for Your Big Ideas
The Lumos Mini is a beautiful and infinitely refillable fineliner, writing, and brush pen, including 9 professional artist's tips and 2 writing tips, all in a compact, pocket-friendly package.
Too many pens are disposable by design, contributing to the unfathomable 100 billion biros now sitting in landfill. Much like printer cartridges, pen companies encourage waste by locking you into their format, selling endless replacements that are bad for the planet and stifle creativity.
As a product designer and craftsman, I’ve spent years designing and handcrafting calligraphy and fountain pens for creatives across the world. However, I noticed that the pens I used most often – fineliners and writing pens – were some of the worst offenders for disposability. Either they ended up in a drawer waiting for hard-to-find refills, or I was reluctant to throw away an otherwise functional pen simply because it had run out of ink.
The Lumos Mini solves this problem, offering all the versatility of its big brother in a portable, pocket-friendly form. A beautiful and infinitely refillable fineliner, writing, and brush pen, including 9 professional artist's tips and 2 writing tips. Its refillable system allows you to customise your pen with a variety of nibs and ink colours, reducing waste and empowering you to create without compromise.
We love it paired with the Lumos Loop – a clever extra lid that keeps your Mini within easy reach on your keys, bag, or lanyard. A perfect match of portability and creativity. Learn more about the Lumos Loop here.
Designed for creatives, by a creative, the Lumos Mini is a beautiful and sustainable answer to disposable pens – proving that good design can be both functional and planet-friendly.

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

Brilliant ink for bold ideas!
fantastic quality and very fast delivery
Lumos loop - great size for writing with. I have mine on my teacher’s lanyard and use it for live marking. It’s a game changer as I am always forgetting to pick up a red pen from my desk. So pleased with the purchase. I’ve tried out different nibs and like the fact this comes with the choice.
Oh my I was given this as a gift and it’s beyond beautiful. What a product
love the colour. such a good pen to write with.
such a nice pen to write with. love that it has many different nibs aswell to pick and choose
- 5 stars: 312 (85%)
- 4 stars: 32 (9%)
- 3 stars: 16 (4%)
- 2 stars: 5 (1%)
- 1 star: 4 (1%)
But less than a week hanging on my lanyard at work the coating is coming off - wish I had got a metal finish but it was more expensive-?I am very happy with the nib hence buying a mini version of the Lumos which I use at home
I bought a Lumos Mini several months ago to use as my "everyday carry" writing pen. The construction of the pen is so solid and dependable, and the quality of the nibs is untouchable. It's a thrill to see sustainability so beautifully combined with the very best mark-making experience.
I inquired a while back about the detail brush nib, asking if it would be suitable for me, given that my preferred pen for drawing has been a Tombow Fudenosuke (Hard). The Tom's team very honesty and kindly replied that, no, I would probably find it too soft. Since I needed some reservoirs anyway, and because the nibs are so inexpensive, I decided to try my luck and add some detail brush nibs to my order.
My order arrived today, and I was overjoyed that the detail brush nibs were so small. I tested one out, and... wowee, it's wonderful! Yes, they're slightly softer than the Tombow, but not by much, and it just makes for a more expressive line.
I've just purchased another Lumos Mini to be my dedicated forever drawing pen. No more throwing out a big plastic body because the nib has lost its shape or the pen has gone dry.
Thanks so much for creating these great products!
My Lumos Mini ‘out in the wild’. I have several ’Tom’s’ pens…this is by far my fave!
I love writing and I love enhancing the experience with a beautiful pen. I recently purchased the Lumos Mini and the Wren so that I could write and illustrate my haiku journal. I was so impressed that I immediately purchased the Field Mouse. I now have a tiny pen in my pocket to record my tiny poems whenever inspiration strikes.
I thought I wanted a traditional fountain pen with a metal stub-type nib until I was introduced to this beauty, and love the outstanding craftsmanship. This is truly a unique piece and will serve me well for years!
I adore this little pen. No leaks, writes beautifully and easy to fill. And it’s so CUTE!
The matte finish does have a strange texture (for those who are sensitive to that).
I only wish there was an option for a pen clip! This pen is too thick to fit standard elastic pen holders. I’d love a way to clip it to my notebooks. :)
All in all I love this pen and will likely get a full size Lumos in the future.
Absolutely in love with this pen! 5/5 stars! Would definitely recommend.
My brother spoilt me with a lumos pro for Christmas which I cannot rave about enough so I decided to treat myself to an on the go compatible version with the mini. They really are beautiful pens, which are beautifully made.
The full collection of tips, even with the mini was a pleasant surprise.
If I was to pick on (very minor) point, it’s that the lavender colour is more on the silver then purple side but for such a lovely pen to use that’s something I can see past.
I am totally happy with the Loop for my new mini Lumos in Lilac. Now I can hang it on my neck as a functional accessory and won't ever lose it! The Loop and the Grip & Rollstop in Natural Leather are two indispensible accessories I will definitely get whenever I buy a Lumos pen. I hope the complimentary 3ml ink will be in matching colour with the pen. That will add a lot of fun using the pen. I also hope that will be a leather pen case for all the Lumos and The Wren to keep them neat . Thank you Tom, for creating such a beautiful pen.
I received my package of a mini Lumos with its 11 tips and a 3ml bottle of black ink, together with a leather Rollstop, spare ink reservoirs and containers and a sachet of Popcorn Tea yesterday. I had been looking for refillbale fineliners and soft tip brush pens with exchangebale partts for a long time. The Lumos ended my search forever. Its sleek and compact design, its mini size, its beautiful colour are all impressive. More than that is the satisfying writing experience of the tips. The leather rollstop makes holding the pen very comfortable and is a good investment. A larger barrel size to increase comfort of grip will be even better (especially for men's hands). I hope the these mini pens are stackable if there were a adapter for connecting them. Building a longer Lumos (like the Pro version) with 2 mini Lumos of different colours would be fun. I would love to see these pens being used as flourescent markers as well if there were compatible flourescent ink from Tom's Studio and wider chisel tips.
I hope Tom's Studio would have retail shops in Hong Kong (where I live) because shipping charge is very expensive from UK to Hong Kong. Now I want to try the Wren as well knowing that the Write-off Version is anow available. Mix-and-match is fun. Hope there will be pen clips , pen pouches as well as other types of tips for use with the Wren very soon.
Super stylos, j’aime tout! Leurs tailles, les couleurs, les pointes interchangeables. Je suis fan!
I’m super happy with the Lumos Mini it’s a superbly designed and very well made little tool,the box contents are now a part of my everyday carry,this is my first purchase from tom’s studio it certainly won’t be my last.
The texture of the pen really surprised me, it's a grainy like texture when I was expecting something smoother and it's feels very wrong on my finger tips. I'll admit though that it's a really personal feeling and does not reflect on the quality of the pen. That being say, the tip set is incredible and I really like the wide range of writing that it provides. The tips seem to be of a very good quality. I also like that the pen cap can be screwed at the end of the pen but it does leave a hole there when the pen is closed with its cap. The global aesthetic of the pen is nonetheless very pleasing.
Hey Manon, thanks for leaving a review! The Midnight and Matte Black colourways of the Wren do have a different finish compared to the other colours in the range, designed to provide a more ‘grippy’ option for customers who find grip to be an issue.
If you haven’t inked it up yet, we’d be happy to proceed with an exchange for a different colourway! Just reach out to us at hello@tomsstudio.co.uk, and we’ll sort it for you. Warm wishes, Rachel
i was not prepared for the smoothness of the parts. it is so easy to take the components apart to change writing tips or reservoir, and the cap seals up so precisely. the tips surpass any fineliner i've used (and i have used MANY). the inks are gorgeous. i love this pen so much, i bought another, and am trying to convince a local stationery store to carry tom's studio products.
Bought the Lumos mini as my first purchase for quick writing, sketching and journalling. I'm so happy with it, the ease and fluidity of the writing, the no fail reloading of ink, the inter changeable nibs and brush that's so versatile. I'm now in the process of ordering the Lumos, the original. A pen for all seasons. Thanks for such a clever invention.
I was bought one of these for Christmas in the colour Ivy and it’s stunning. I couldn’t have asked for a better pen to go in my art kit.
There I was sat on my sofa Christmas Day doing a quick sketch and trying the chisel tip for writing which you have to excuse as I’m only just learning calligraphy
Hi Pauline, thanks so much for leaving a review! The Lumos Matte Midnight and Black colour option does tend to show marks a bit more than our anodised colours due to the matte finish. That said, these marks should usually come off easily with a damp cloth. I noticed we've reached out to offer an exchange for a different colour, but you've chosen to stick with the one you have. Please do let us know if you change your mind and our team would be more than happy to help. Warm wishes, Rachel
I have a favourite colour that I like to draw in. I can’t stand black and have searched high and low for something refillable and a please to use. These so far have been that. Modern technology, no spills like with fountain pens (nibs are so scratchy anyway)
And my colour flavour of the month.
I recommend the long barrel over mini for comfort. But start where you can.
Looking forward to Tom adding blue to his range of barrel colours. (My favourite colour esp a royal/navy blue)
Lumos mini became my favorite objet. It’s a pleasure to write and sketch. It writes beautifully.
I adore this pen, it writes beautifully. So smooth! It is a bit short to write with without screwing the cap on the top when you write, but it is a small pen! I got it due to the cost of the bigger ones rather than size, but am now saving up for a full sized one as I can’t imagine using another pen now. I am a pen addict and like to get new pens and often switch several times a day between them, but I’ve honestly not picked up another pen since I got this one. The first fill of ink is still going, I’m amazed as I write a lot. My fingers are getting a little old and I’d quite like a thicker pen if they ever make one for ease of grip, but I think the weight of the brass version might work the same and I like the look of that one best of all. It is on the birthday list!
