• High quality: Made with stainless steel and medical-grade plastic, the tattoo cartridge needles ensure durability and safety. The transparent tip body enhances visibility during tattooing. • Easy to use: These needles are essential for tattoo artists. They are sharper, pierce the skin quickly, and operate stably. Their design allows for better ink flow and a contoured interior. • Professional design: The needle's membrane system keeps the amount of liquid consistent with each stroke. The rubber plug connection offers good elasticity and prevents ink from flowing backward. • Sterilized needles: Each needle is sterilized and individually packaged to ensure hygiene. They are compatible with all standard cartridge grips and machines. • Package contents: 20 mixed units of tattoo needles (3RL, 5RL, 5M1, 7M1).
