The STIGMA Aquamarine Knight EN02B Series disposable tattoo needle cartridges feature a sterilized membrane and are designed by tattoo artists for precision and safety. Made from 304 surgical stainless steel and medical-grade plastic, they are E.O. sterilized and packaged in a blister pack, including sizes 1203RL, 1205RL, 1207RL, 1209RM, and 1215RM. The transparent light blue design symbolizes healing, while the sloped round tips and arched flat tips ensure detailed artwork. Rubber band-loaded cartridges with a plastic membrane prevent ink backflow, and they are compatible with standard cartridge tattoo machines and grips for convenient use.
