Durable, reliable cartridge needles designed for consistent performance in frequency tattoo work Key benefits Stable needle action: Silicone case provides strong toughness and reliable resilience. Needles remain elastic during long periods of frequency operation and vibration is reduced for steadier strokes. Smooth, precise coloring: Needle wire made from 304 stainless steel with an ultra fine thread. The fine construction reduces skin trauma while maintaining resilience to match fast machine movement for efficient coloring. Fewer interruptions: Larger ink storage in the cartridge reduces the need for frequent color refills and helps prevent inkjet, keeping workflow smoother. Broad compatibility and easy identification: Complete range of needle models fits about 95 percent of tattoo machines on the market. The transparent case lets you quickly see the needle model before use. Product attributes Case material: resilience silicone that cushions needle movement and resists deformation under extended use. Needle material: 304 stainless steel needle wire that is designed to be nonreactive to skin contact and maintain consistent performance. Needle design: Ultra fine needle thread for reduced skin impact and fast pigment deposition when used with frequency machines. Cartridge features: Increased ink chamber capacity and antiinkjet design to minimize splatter and interruptions. Compatibility: Wide model selection designed to work with the majority of tattoo machines; transparent housing for easy model checking. Use scenarios Color packing and large fills: Larger ink capacity and stable needle action let artists work through large color areas with fewer stops to reload pigment. speed shading and color transitions: Ultra fine needles and resilient wire match frequency machine movement to produce consistent shading and rapid coloring. Detailed linework and precision tasks: Stable needles with low vibration support controlled strokes for fine lines and detailed work. What it solves Reduces needle instability and vibration that can affect line quality. Minimizes downtime for color changes and reduces the chance of ink splatter. Delivers consistent needle response for both speed machines and longer sessions. Suitable for professional and freelance tattoo artists who need durable cartridges that maintain performance during extended, frequency use.
