JCONLY® VETAR Round Liner (RL) Cartridges – Precision Outlining & Detail Work

Engineered for ultra-precise line performance. The VETAR RL cartridges feature high-precision needle welding technology, ensuring maximum stability and consistency during fast hand movement. Designed specifically for fine line tattoos, lettering, geometric patterns, and detailed realism outlining, they deliver clean, sharp, and controlled lines with minimal vibration or deviation. The reinforced structure improves needle stability and reduces wobble, making RL cartridges an essential tool for professional tattoo outlining workflows that demand accuracy and clean execution.

1. Medical-Grade Safety – Protect Your Reputation

In professional tattooing, safety defines trust. VETAR cartridges are crafted with medical-grade PC housing and Japan-standard stainless steel needles, ensuring a sterile and reliable working environment for every procedure. Strict manufacturing control guarantees consistent needle sharpness and stability, supporting everything from fine line tattooing and black & grey shading to color packing with professional-grade reliability you can depend on.

2. Ergonomic Control – Reduce Fatigue in Long Sessions

Long tattoo sessions require more than precision—they require endurance. The VETAR cartridge features an ergonomic shell design with a textured anti-slip grip and concave back support, improving finger stability and machine control. This reduces hand fatigue, helping tattoo artists maintain steady needle depth, smooth hand movement, and consistent accuracy throughout the entire tattoo process.

3. Optimized Ink Flow – Continuous Tattooing Without Interruptions

A stable workflow starts with stable ink delivery. The integrated capillary reservoir system uses a funnel-shaped internal structure to optimize pigment storage and flow consistency. This ensures smooth, uninterrupted ink output for clean linework, soft gradients, and efficient color saturation—eliminating dry hits and inconsistent flow that can disrupt your tattoo stencil-to-skin workflow.

4. Anti-Backflow & Universal Compatibility

Each VETAR cartridge is equipped with a precision-engineered silicone membrane system that prevents ink backflow, protecting your rotary tattoo machine or wireless pen from contamination. Designed for fast-paced studios, VETAR offers broad compatibility with all standard rotary machines, wireless pens, and cartridge grips. The secure snap-in system allows fast installation, keeping your studio workflow efficiency at its highest level.
