TWSBI Diamond 50 Ink Bottle – Polished Aluminum

Get the most out of every ink drop with this ingenious, clean-filling ink bottle from TWSBI (commonly pronounced “twiz-bee”). The two-part aluminum cap unscrews to provide multiple ways to fill your pen.

Remove the very top of the TWSBI-logo cap to directly fill your TWSBI Diamond 580, Classic, Mini or Precision fountain pen. You can also fill international converters by attaching it directly to the adapter. Unscrew the bottom part of the cap so you can fill any other pens as you would a traditional ink bottle.

The faceted shape of the 50ml glass ink bottle gives your ink color a beautiful home to show its brilliance. Ink is not included.
