Fountain Pen Converter 800A

This excellent piston-style converter allows any Platinum fountain pen (and also certain models from Kuretake) to accept fountain pen ink from a bottle. Simply pop it into the pen where the ink cartridge would normally mount, then draw ink through the nib and into the converter by twisting the piston. Platinum converters are solidly built and easy to use, with a secure mount that prevents leakage.
