needle cartridge designed for precise, reliable tattoo work. Built from corrosionresistant materials with a polished needle surface and a transparent cartridge tip for clear visual control of ink flow. Key benefits Durable, corrosionresistant needle tip made of 316L stainless steel with a polished surface for smooth penetration and reduced drag. Cartridge construction uses 304 stainless steel for components other than the tip and transparent medical grade plastic for the tip, enabling clear observation of ink absorption. Nanosilica gel insert provides soft elasticity and low resistance, helping reduce vibration and wear on the machine motor. Internal membrane reduces ink backflow into the tube or machine, minimizing mess and maintenance. Semitransparent, bevelshaped tips allow easy monitoring of needle movement and ink uptake during work. quality silicone maintains needle elasticity and consistent stroke performance. Individually packaged cartridges for clean handling and convenient storage. Materials and function Needle tip: 316L stainless steel, polished for smooth contact. Needle body and nontip components: 304 stainless steel. Cartridge tip: transparent medical grade plastic for visual monitoring. Gel and sealing: nanosilica gel for low resistance and silicone for elastic support. Function: disposable cartridge system for controlled ink delivery and reduced backflow. Use scenarios Detailed color packing in studio sessions where visual monitoring of ink uptake improves control and color consistency. Shading and gradient work requiring smooth, lowdrag needle performance and stable motor operation. Frequent sessions or volume workflows where reduced maintenance and reliable cartridge sealing help maintain productivity. Compatibility and handling Designed as a cartridgestyle needle assembly for use with cartridgecompatible tattoo equipment. Follow your equipment manufacturer guidelines for installation and operation. Store cartridges in a clean, dry place and handle each cartridge by its body prior to seating to maintain cleanliness. This product emphasizes durable materials, visual control of ink flow, and components that reduce resistance and backflow to support consistent tattooing results.
