Description

When you’ve found an ink you truly enjoy, it makes sense to have a generous supply—and TWSBI’s 70ml Fountain Pen Ink bottles deliver exactly that, with a few clever refinements thrown in for good measure. Designed by TWSBI, this larger-format bottle is made for regular writers who prefer refilling pens over constantly topping up ink shelves.

Each frosted glass bottle is fitted with a special nozzle that allows you to use every last drop of ink, right down to the very bottom—no tilting acrobatics required. Better still, the bottle is compatible with the cap of the Diamond 580 ink bottle, allowing for clean, controlled, and mess-free filling of your TWSBI 580 fountain pen. Sensible engineering, quietly doing its job.

Available in a small but well-chosen palette of classic colours, these inks are formulated for smooth flow and dependable performance, making them equally suited to long writing sessions, note-taking, or everyday correspondence.
