This 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 (eg Diamond 580, Diamond mini etc) piston-filling pens to be filled by removing the nib unit and connecting the barrel directly to a filling tube in the coloured aluminium part. This method can also be used for filling standard size converters from other makes of pen.
Note that this is the version with aluminium parts.

Nib choices for fountain pens
If we show the pen with the default nib selection shown in stock it means we have stock of that pen. If you select another nib size and the website doesn't say "in stock" we can usually supply that pen immediately as we keep extensive supplies of nibs from all our manufacturers.
