Diamond Inkwell TWSBI 50ml

• The TWSBI Diamond 50ml ink bottle is a glass bottle with an anodised aluminium cap.
• The bottle allows for easy refilling of the fountain pen by providing a top reservoir which fills with ink when the bottle is turned upside down (with the cap on).
• The reservoir provides a set amount of ink to fill the pen and avoids the hassle of dipping the pen into the bottom of the bottle, trying to squeeze out every drop as the bottle is running low.
• As an added benefit for those who own the Diamond 530, 540, 580 or Mini fountain pen, you can use the coloured band accessory to refill your TWSBI fountain pen without having to use the nib at all. Simply unscrew the front section of your Diamond fountain pen and connect it to the filling device. If you turn the piston knob of the fountain pen, the ink will flow into your pen.
