About This Product

These empty fountain pen cartridges are compatible with Kuretake cartridge brush pens, plus all Platinum fountain pens (the two companies use the same cartridge format, easily identifiable by the ball bearing that caps each cartridge.)

Five cartridges are included, plus five ball bearings and a dropper that's perfectly sized to fill them with bottled ink.

Made in Japan.
