An upper reservoir that fills with ink when you turn the bottle upside down (cap on of course!) allows you to get all of the ink from the bottle without having to chase the last drops around the bottom of the bottle. If you have a Diamond 530, 540, 580 or Mini fountain pen you can use the colored band attachment 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 attach it to the filling apparatus. Turning the piston knob of the fountain pen will draw the ink up into your pen. No more inky fingers!!
