Polaroid branded cartridges are 100% remanufactured. This means that they are cartridges that were originally manufactured by the same manufacturer as the printer, and have then been depleted. These used cartridges are then collected and returned to the remanufacturer where they are then refilled to the most exacting standards.
Each inkjet cartridge is thoroughly cleaned internally using bespoke centrifuge machines and de-ionised water (as normal tap water is not pure enough!)
