Refillable Fibre Tip Pen | Lumos Pro - Single Tip | Ivy

Lumos Single Tip Pen — Refillable Fineliner & Brush Tool for Creative Writing & Illustration

The Tom's Studio Lumos Pro in Ivy Green is a precision-engineered, infinitely refillable fineliner, writing and brush pen designed for creators who reject disposable tools. Made from durable anodised aluminium and includes a full set of professional-grade tips covering fineliner, felt and writing styles.

The single-tip design gives you one robust tool with a generous ink reservoir that runs longer between fills. Ideal for illustration, lettering, sketching and everyday writing, Lumos blends practical versatility with thoughtful sustainable design — perfect for designers, illustrators and pen lovers who value control, build quality and refillable simplicity. Compatible with fountain-pen inks and supported by replaceable tips and reservoirs, it’s built to last without excess waste.

To use it, simply dip the internal reservoir into your favourite fountain pen ink and watch it draw up a fresh supply in seconds. The Japanese-made fibre tip provides a smooth, consistent flow similar to a premium rollerball but with the customisation of bottled ink.

• Precision CNC machined from aerospace-grade anodised aluminium.

Tom’s Studio began in a Dorset workshop when founder Tom Gyr, a furniture maker and blacksmith, watched his wife, Gemma, struggle with mass-produced, disposable calligraphy pens. Using a 1960s lathe, Tom engineered a precision-balanced pen designed to last forever.

Today, this UK-based brand leads the "refill-ution," moving away from plastic waste toward sustainable, luxury stationery. Every fountain pen, dip pen, and bottle of pigment-rich ink is crafted with an artisan’s eye for detail. Perfect for artists and writers, these tools blend traditional craftsmanship with modern ergonomics to make every mark on the page feel effortless.
