A precision-engineered Lumos Brass Duo Tip pen, created as an elegant and infinitely refillable alternative to disposable fineliners. Crafted from solid brass, this special edition Lumos offers a satisfying weight, a smooth polished feel, and exceptional balance in the hand—designed to bring lasting joy to creative and everyday work. Inspired by classic British industrial design, from vintage cars to old transistor radios, every detail has been carefully considered. Features such as the finely knurled cap and the secure, tactile closure reflect the heritage and craftsmanship behind the design. Each pen is manufactured locally using high-precision lathes typically used for watchmaking and aerospace components. The Duo Tip design allows you to use two different tips or ink colours within one pen body, making it ideal for artists, designers, and writers who value flexibility without carrying multiple pens.

Duo Tip Design
The Lumos Duo is designed so that one half of the pen acts as the lid for the other. One tip is capped, while the second tip is securely stored by screwing it into the centre of the pen. This keeps the pen compact, balanced, and secure—without the need for extra lids. Extra lid is sold separately.
Ink Compatibility
Compatible with dye-based fountain pen inks that do not contain particles or binders.
Not suitable for shimmer, acrylic, shellac, or particle-based inks.
Exception: Compatible with waterproof pigment inks such as Sailor Kiwa-guro and Platinum Carbon.
