A beautiful and infinitely refillable fineliner, writing, and brush pen, including 9 professional artist's tips and 2 writing tips

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 - (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 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.

    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 all but the most experimental fountain pen inks (think shimmer + iridescent). We offer a beautiful range of pigment ink for fountain pens, which are perfect for the Lumos and can be found here.

    Note: Calligraphy Ink has an acrylic binder which will block the pen and is not suitable for use with The Lumos.

    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.

    We aim to process your order within 1-3 working days. Please note that this increases to 1-4 working days for orders that include any personalisation, such as engraving.

    I bought this for my dad for Fathers Day. He is going to love it!

    If you love pen’n’ink you’ll love this pen

    Easy to fill the only thing that would make the duo better is two metal end caps.

    Perfect pen

    I love my Lumos pro so much. The weight, balance, feel and ease of refilling are all I could have asked for in a perfect pen. It’s glorious! Such a high quality nib and pen. I’m a teacher, so marking papers is a regular practice, and this pen will save so many disposable’s from being thrown away. Thank you Tom’s Studio.

    I love this pen!

    I’m a stationery lover and have a couple of luxury fountain pens, so when I saw the Lumos I had to give it a go, and I’m not disappointed.

    The pen is lovely to use and is a nice weight, and writes like a dream!! I love the fact that you can use different colour fountain pen inks, which I may of bought 4 of! I will definitely be buying another pen at some point and collecting the inks. A very worthwhile investment!

    I love this pen!

    I have never had a pen like this. It writes easily, refills easily and allows you to change inks without a lot of involved cleaning. Thank you!
