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 that they can keep selling you replacement pens or refills over and over again.  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 its self."
David Downton - (one of the world’s leading fashion artists)

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 loathed 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 its disposable nature: the fineliner.

    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).

    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:

    Easily swap colours

    Airtight containers allow you to easily swap colour filled reservoirs in and out with ease.

    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 11 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.

As I am very pleased with the great versatility of the Lumos, it felt natural to share the news ! It is always a pleasure to discover people passionate about their work and who makes great creative tools ! YouTube video placeholder

    Amazing Pen

    I really love the lumos. It is so high quality- and feels like it looks. To write and letter with it (no matter if fine oder brush) feels really perfect, since it lays wonderful in your hand. I'm happy to start a new lettering adventure with my lumos! 🥳👏🏼

    Really love the way it writes!

    I really, really like the Lumos pen -- it's flow is terrific and I love that I have an option of tips. A few bits of feedback: it wasn't clear to me when purchasing that the "pack" came with multiple tips. It does -- and it's great to be able to switch between tips! Better clarity/marketing on the website about what exactly the starter pack contains would be helpful. Also: the instructions on changing tips etc. are really lacking and could be more robust. (I got an immediate response to my query via email which is terrific. But one shouldn't have to write for instructions). Finally: I got the single not dual tip Lumos, and, having used it for some weeks now, I wish I'd gotten the dual. (Note: it is confusing that the pack includes "multiple tips" but there is an option to get a "single" vs "duo tip"). If you want/use multiple colors, get the dual. B/c I got the single, I had to then invest in additional "fillers/cartridges" so I could swap out colors. Yes, one can buy additional refills and little tubes to store the fillers in, but it's a closed system and that seems anti-sustainable which is the very premise Lumos counters.

    Thank you so much for your review, we're so pleased to hear that you're enjoying your pen! Those are some really valid and useful points and will definitely use them to improve they way we communicate the Lumos moving forward. Thank you for taking the time to send this feedback over! Best wishes, Gemma

    Love this pen

    Easy to fill and love writing with it.


    Absolutely stunning!! The weight feels lovely in my hand. I have used two of the nibs so far (bullet and brush), and I am over the moon for it!! Would definitely love to collect the other colors in the future! 😍
