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 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:

    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 (our own No.60 Fountain Pen Waterproof in Pigment Black). Or, if you want to splash out, Sailor Kiwa-Guro ink is a great option too.

    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:

    Great pen,

    One of the best pens I've bought. Will get another to keep in my bag. The current one stays in the office. Writes lovely and feels lovely in the hand.

    Words, Words and more Words. All crafted with the magic of my Lumos Pro

    I was lucky to have a birthday recently, and I am now the proud owner of an inscribed Lumos Pro. A lifelong scribbler, my Lumos Pro makes me even more committed to writing short stories and poetry. I have yet to try all the tips and I’m looking forward to making time to use them in sketching the natural world around me.

    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. 💖

    Project Darabion, powered by the Lumos Duo Pro.

    Wow

    I can't rate this pen highly enough. It feels amazing and lovely to use. My handwriting looks amazing and it's so versatile with the different nibs. I also love that I can store different coloured inks in the reservoirs which makes it so easy to swap colours. If your thinking about buying this pen you should do it, you will not regret it!
