This glass ink bottle is the perfect accessory for any fountain pen user. The bottle can be used with any fountain pen that uses bottled ink, but its unique two-part anodized aluminum cap provides a special filling method for TWSBI Diamond fountain pens. Removing the upper cap reveals a filling port that plugs directly into the barrel of your TWSBI Diamond fountain pen, allowing you to draw ink up from the bottom of the bottle without any mess or risk of spilling. For those who prefer not to use this filling system, the lower cap can be removed, and the upper cap can be screwed directly onto the bottle. A removable plastic reservoir makes it easy to draw ink from the bottle even when the ink level is low. Simply flip the bottle upside-down and back to fill the reservoir.
For protection, the bottle is packaged in a cardboard box. This cardboard box is fragile and may get crumpled during shipping.
Ink is not included.
