Kwadron Tattoo Needle Cartridge Box of 20 - 9 Round Shader #12 Long

Our review of the Kwadron Tattoo Needle Cartridge box of 20 finds it best suited for artists who need consistent, precise round shading during multi-pass work. The single biggest reason to buy is the stable, low-friction design that combines a membrane to prevent ink backflow with a medical grade plastic housing, delivering reliable performance and gentle handling on skin. For anyone using cartridge machines for shading, these cartridges offer predictable grouping and razor-sharp surgical steel needles that make blending and soft gradients easier.

Key Features

• Stabilizing system: The unique stabilizing system improves accuracy and keeps the needle grouping steady for cleaner, more controlled shading strokes.
• Membrane protection: A full membrane prevents ink backflow, helping maintain hygiene and reducing the risk of contamination during long sessions.
• Plastic housing: Medical grade plastic housing reduces friction between the needle group and tip, allowing smoother gliding and less drag on skin.
• Surgical steel needles: Razor-sharp steel needles are precision made to deliver consistent penetration and predictable healing characteristics.
• Box quantity: One box contains 20 cartridges, offering a ready supply for busy sessions or to test a new needle configuration.

Who It's For
