Kwadron Optima Permanent Makeup Cartridge 4 Flat Shader.35mm - Precise

Our review of the Kwadron Optima Professional Permanent Makeup Cartridge finds it best suited to artists who need consistent, fine-detail shading in permanent makeup work. The single biggest reason to buy is the cartridge's reliable construction: medical grade plastic, surgical steel needles and a membrane system that protects against backflow give a technician confidence during close, precise work. For anyone doing delicate brow shading or microblading-adjacent shading, this box of 20 4 flat shader.35mm cartridges delivers predictable ink flow and stability that matters when working on small areas.

Key Features

• Medical grade plastic: durable housing keeps the needle stable and comfortable to handle during long sessions.
• Surgical steel needles: corrosion-resistant needles maintain sharpness for accurate, repeatable lines and shading.
• .35mm needle diameter: a fine point taper that is suited to precise shading and small-detail work without excessive trauma.
• Membrane backflow protection: prevents ink from entering the machine, improving hygiene and reducing cleanup.
• Optimal ink flow: the internal design supports consistent saturation and reduces the need for repeated passes.
• EO gas sterilized: ethylene oxide sterilization ensures cartridges arrive sterile and ready for single-use procedures.

Who It's For

The Kwadron Optima 4 Flat Shader.35mm is aimed at professional permanent makeup artists and experienced tattoo technicians who prioritize precision and hygiene. It is especially appropriate for artists working on eyebrow shading, soft ombre effects, and clients who require subtle, controlled pigment application.

It is not intended for hobbyists who seldom perform procedures or for technicians who need very coarse, heavy shading; those users should consider larger configurations or different needle types. New trainees should ensure they are trained in handling cartridges with a.35mm point taper before using these on clients.
