TWSBI Diamond 50 Ink Bottle Silver
TWSBI Diamond 50 Ink Bottle Silver
£24.99
This silver TWSBI Diamond 50 ink bottle features an internal reservoir for easy filling even when the level in the ink well is low (compatible with all fountain pens). A unique feature also allows for the barrels of TWSBI Diamond series piston-filling pens (ie without nib unit fitted) to be filled by connecting directly to a filling tube. This method can also be used for filling standard size converters.

Note that this is the version with aluminium parts.
