TWSBI Diamond 50 Ink Bottle
The TWSBI Diamond 50 Ink Bottle is a beautifully designed glass bottle with an anodized aluminum cap, made to simplify and enhance your fountain pen refilling experience. Suitable for all fountain pens, it features a clever upper reservoir system that fills when the bottle is inverted (with the cap securely on), allowing for easy access to ink even when levels run low with no need to dip your nib deep into the bottle.
For TWSBI Diamond 530, 540, 580, and Mini fountain pen users, there's an extra bonus: a special filling cap is included that lets you refill directly by attaching the pen's barrel, completely bypassing the nib. Just remove the front section, screw the barrel onto the adapter, and twist the piston knob to draw ink - clean, convenient, and no inky fingers.
Note: Ink not included.
