TWSBI VAC 20 Ink Bottle - 20ml

The TWSBI VAC 20 Ink Bottle is a neatly engineered solution for anyone who prefers refilling fountain pens without theatrics—or stained fingers. Compact, practical, and refreshingly sensible, this plastic inkwell is designed to make filling TWSBI vacuum pens calm, clean, and thoroughly predictable.

Holding up to 20ml of your chosen ink (not included), the VAC 20 features a clever upper cap design that allows you to fill compatible TWSBI pens directly and securely. Simply attach your pen, draw ink, and carry on with your day looking as though nothing dramatic happened. For non-vacuum pens, the upper cap can be removed entirely, turning the bottle into a standard inkwell for more traditional filling.

Designed by TWSBI, this inkwell is a quietly excellent companion for writers who value efficiency just as much as ink.
