Diamond 50 Ml Ink Bottle

This cleverly designed ink bottle from TWSBI lets you fill your fountain pen in multiple ways. For those who use a TWSBI Classic, Diamond, Diamond Mini, or Precision fountain pen, the top of the ink bottle has a compatible filling port that lets you plug the pen’s barrel directly into the bottle to draw ink, leaving your nib clean and dry.

The filling port can also be removed so the ink bottle is compatible with any fountain pen. This bottle is designed to let you draw ink even when the ink level is low by using its removable plastic reservoir. You just flip the closed bottle upside-down to fill the reservoir, then flip it back to fill your pen.

• Holds 50 ml of ink
