As someone who has made calligraphy pens for some of the world's most talented calligraphers, I know how important it is for them to use a beautiful pen that feels worthy of their beautiful work. Brush lettering is also an amazing pursuit, but unfortunately, many of the pens available are disposable. My wife, Gemma, has a "drawer of shame" that's full of perfectly good pens that have either run out of ink or have worn tips.

To put an end to this pen purgatory, I designed the Lumos, a refillable brush pen with replaceable pen tips. With the Lumos, you can customize your pen and refill it with any color fountain pen ink, of which there are thousands (and some rather lovely ones, even if I do say so myself). Refilling your pen is easy--simply dip the reservoir in ink, and through the magic of capillary action, it will draw up all of that inky goodness. You can easily change colors in the pen by rinsing the brush tips and reservoirs or swap out with entirely new tips and reservoirs, replacements for which you can find here.

The included brush tip itself is an absolute dream, with a good balance between firm and soft, sitting between a Pentel and a Tombow. Having been road-tested by some excellent brush letterers, it also punches above its weight as far as durability goes. It's not surprising, as they are made in Japan by the world's top tip manufacturers.

The Lumos also has interchangeable tips, so you can turn it into the perfect pen for illustration or writing in a jiffy! I have a selection of nine amazing tips for drawing, starting from the smallest 0.1 to 1.0. These professional-grade fineliner tips remove the need for buying a disposable pen for each size. I've also just introduced writing tips, which are incredibly durable and wonderfully smooth on any paper. They're also great for drawing.
