These refillable cartridges are made of sturdy and clear high-quality polypropylene plastic. They insert into your EPSON R3000 printer easily. This cartridge is a perfect marriage of the best designed cartridge with the best designed microchip. Final assembly is produced at Vermont PhotoInkjet. Of special note is our ultra-large 60mL cartridges. These are unique to InkjetMall and we recommend them over the 30mL carts.
