Kwadron Hybrid System Round Liner – precision that keeps the line

This professional cartridge is designed for both beginner and experienced tattoo artists who value clean, sharp, and stable contours. It is engineered to ensure smooth movement across the skin, controlled guidance, and accurate rendering of shapes, including the finest details. The Hybrid System increases needle stability, reduces vibrations, and supports perfect ink flow for consistent performance even during longer strokes.

What makes the Hybrid System different

• the circular arrangement of tips ensures an accurate and straight contour,
• a firmer needle movement allows for a clean line,
• the optimized internal construction improves work with colour,
• the medical-grade plastic body minimizes friction and supports smooth operation,
• a reliable solution for all-day sessions.

What is the difference between Round Liner (RL) and Round Shader (RS)?

Kwadron Hybrid System Round Liner – the needles are arranged very tightly in a circle and their tips converge into a single point. All punctures therefore aim at the same spot, which is ideal for precise outlines, fine lines and small details.

Kwadron Hybrid System Round Shader – the needles are also arranged in a circle, but their tips do not point to a single spot. They remain more parallel to each other, which provides a gentler contact with the skin and smooth shading suitable for soft transitions and filling larger areas.

Suitable tattoo styles – balance between technique and feel

Ideal for:

• sharp contours and precise strokes – stable guidance and clear definition,
• detailed work – micro-details, thin elements, technical lines,
• lettering and calligraphy – readable, consistent appearance,
• traditional and neo-traditional style – strong, high-contrast outlines,
• illustrative designs – even lines for a technically clean composition.

Available configurations

Kwadron Hybrid System Round Liner is produced in diameters 0,30 mm (#10) and 0,35 mm (#12). Fewer needles create a finer and more detailed stroke, while a higher count delivers a wider and more pronounced contour, which allows you to adjust the choice according to your style and the desired visual result.
