The TWSBI Diamond 50 ink bottle is uniquely designed 50ml glass inkwell with an anodised aluminium cap that is the perfect accessory for the TWSBI Diamond fountain pen range.

It has a strikingly modern and eye-catching design, with clear faceted glass and precision-made aluminium filing mechanism as part of the cap. Its internal reservoir allows for easy refilling of any fountain pen, even when the ink in the bottle is low. 

For those who own the Diamond 580 fountain pen or any of the Diamond range, the metal lid unscrews to reveal a filling hole that connects directly to your pen. This allows for filling without any spillages, leakages or mess.

The ink bottle is supplied empty but can be used with any fountain pen ink including TWSBI's inks and comes in a range of lid colours including black, blue, red, silver and polished aluminium.



Faceted glass with internal reservoir


Two-part - anodised aluminium in blue, black, red or silver with black screw lid. Polished aluminium version has both parts in polished aluminium.
