Hatchback Pro Cartridges are built for maximum stability and precision. They feature long-taper 316 stainless steel needles, a square internal channel to prevent needle rotation, and a reinforced internal stem system for consistent, controlled linework. Magnum configurations include additional internal stabilization to reduce flex and prevent spitting during shading.

CA Cartridges are also made with 316 stainless steel needles, but use a medium taper, offering a slightly softer, more forgiving feel that many traditional tattooers prefer. They share the same proven membrane system and internal stem design used in Hatchback Pro cartridges, providing reliable tension, smooth needle drive, and clean lining. Many artists find CA magnums perform especially well with thicker pigments and bold color work.

Both cartridge lines use medium-tension membranes for balanced resistance, minimal vibration, and dependable backflow protection. Every needle is inspected before packaging and sterilization to ensure professional consistency and safety.
