Apex Cartridges – Round Liner (RL) Tattoo Needles – Box of 20
Apex tattoo needles cartridges are engineered for artists who rely on accuracy, stability and hygiene in every session. The Apex Round Liner configuration is built for precision outlining and controlled line work, offering smooth ink delivery and steady needle travel for confident, repeatable results.
Each cartridge uses high quality surgical stainless steel needles that are designed to feel sharp, stay sharp and maintain consistent performance throughout the session. Paired with a medical-grade cartridge body that helps reduce internal friction, a responsive safety membrane system and universal Cheyenne-style compatibility, Apex cartridges are ready for professional daily use in modern studios.
Key Features
Designed for precision and controlled outlines
Apex Round Liner cartridges are tuned for crisp fine line work, delicate detailing and precision outlining, while also supporting bolder, stronger outlines thanks to the wide size range available.
Sharp surgical stainless steel needles
Manufactured from high quality surgical stainless steel, the needles offer a clean, smooth entry into the skin and are built to maintain their sharp feel and reliable precision across extended tattoo sessions.
Stabilised casing to reduce needle wobble
The internal stabilisation structure helps support the needle during movement, assisting with reduced wobble and improved accuracy when placing lines.
Safety membrane with responsive rebound
The integrated safety membrane prevents backflow while also providing controlled rebound, giving a steady and consistent needle response even during longer sessions.
Medical-grade cartridge body
Built using medical-grade materials, the cartridge body is designed to reduce internal friction, supporting smoother motion and more consistent needle control.
Tip engineered to hold more ink
The tip design retains more ink, helping maintain smoother flow and allowing longer passes with fewer interruptions while working.
Long taper configuration
Featuring a 6.5mm long taper setup, developed to support refined line definition and stable precision without being overly aggressive.
Perfect for Professional Artists
Apex Round Liner tattoo needle cartridges are ideal for professional artists who specialise in precision outlining, detailed fine line work and structured line compositions. With sizes ranging from ultra-fine liners through to larger RL configurations, they are equally suited to delicate single needle style work as well as stronger, thicker outlines. Consistent stability, smooth ink delivery and premium stainless steel construction ensure Apex cartridges perform reliably throughout demanding studio days.
