The ink volume of these cartridges are 30ml in colour and 40ml in large black. (Genuine cartridges are only 7,5ml in colour and 21ml in large black) and are designed to fill maximum ink, that is a reason we call them  BIG TANK.

Designed to refill ink very easily, all you have to do is take a colour plug off from top of a cartridge.

These cartridges have  plugs attached to make it easy for multiple use. Each plug is coloured to identify the cartridge when refill.

Very easy to check ink volume in these clear skeleton cartridges.

100ml quality dye ink bottles, 4-color set is included in this set. See details for our ink bottles.
