This frosted glass bottle contains 70ml of TWSBI Blue-Black fountain pen ink, and comes with a conical insert for easy pen filling. This color is a modern iron gall and highly water-resistant.

The top of the TWSBI Diamond 50 Inkwell is also interchangeable with the top of these 70ml ink bottles, for another easy way to fill compatible pens.
