Prinker S Inks and Skin Primer are specially developed using cosmetic formula and are listed with FDA's MoCRA, and registered with CPNP (EU) & SCNP (UK) as cosmetic products. Prinker inks are smudge-proof and water-resistant but, at the same time, easily erasable with water and a bit of soap or with make-up remover. Coupled with our Skin Primer, printed designs last longer on your skin. There are two types of Consumable Set for you to pick from. If you'd prefer your temporary tattoos to be in rich black, pick the Black Ink Cartridge. If you want your designs to be in vivid colors and composite black, Color Ink Cartridges are for you! Each cartridge set can last you a minimum of 1,000 prints. The number of tattoos you can print varies according to size and complexity of designs. Compatible with Prinker S.
