Product details
Apex Cartridges – Round Magnum (RM) Tattoo Needles – Box of 20
Apex tattoo cartridges are built for professional artists who want smooth shading control, strong colour delivery and reliable studio hygiene. The Apex Round Magnum (RM) configuration features a gently curved needle formation designed to follow the natural shape of the body, helping create softer edges, smoother gradients and comfortable skin contact while working.
Each cartridge uses high quality surgical stainless steel needles, a medical-grade cartridge body to help reduce internal friction and a responsive safety membrane for stability and backflow protection. Combined with universal Cheyenne-style compatibility and EO sterilisation, Apex Round Magnum cartridges deliver dependable performance for modern professional tattooing.
