TWSBI Diamond 50 Ink Bottle – Silver
The TWSBI Diamond 50 ink bottle is a 50ml glass bottle with anodized aluminum top. This inkwell is a great accessory for any fountain pen addict. This bottle is intended to make any fountain pen ink easy to fill, and it does this with style. Turning the closed bottle over collects the ink in an inner reservoir. Additionally, the opening is wide enough to fit fountain pens of any size. This is just one way the bottle helps with filling.
Apart from the reservoir, another feature of this bottle is the aluminium band attachment. This band has a straw-like metal tube that dips deep into the bottle. Those who own a TWSBI Diamond 580 or Mini fountain pen can use this attachment to achieve a complete fill, without having to use the nib at all. Simply unscrew the nib section, and attach the body of the pen to the small opening, then turn the piston as normal. This feature also applies to any pen with an International Standard converter, as the converter attaches in the same way.
Of course without the gadgety lid, this ink bottle can also be used with regular fountain pens and filled as you would with any other ink bottle.
This version of the bottle features a silver band, and would be a great match for a grey ink.
