These are Kwadron 3 Tight Liner Long Taper tattoo needle cartridges (30/3RLLT) sold in a box of 20, engineered for crisp, consistent lining and smooth ink flow.

Designed for tattoo artists who demand control and fine detail, Kwadron's Tight Liner Long Taper cartridges combine razor-sharp steel needles, a low-friction plastic housing, and an integrated membrane to limit ink backflow.

Each cartridge ships sterile and individually packaged to maintain hygiene standards.

How do these cartridges improve linework quality?

The three-needle tight cluster and extended taper give you a condensed point of contact that pushes pigment deeply and evenly without excessive trauma. That precision helps produce cleaner, more consistent lines and reduces the need for repeated passes.

• 3-needle tight configuration focuses pigment for sharp edges
• Long taper smooths skin penetration and reduces blowout risk
• Razor-sharp steel needles for consistent puncture performance
• Low-friction plastic housing keeps needle grouping aligned

What features protect against ink backflow and contamination?

Kwadron cartridges include a full membrane barrier that blocks ink and fluid from entering the grip and machine, helping protect equipment and maintain a sterile workspace. Individual sterile packaging further reduces contamination risk until the cartridge is used.

• Full internal membrane prevents ink backflow into the device
• Individually sealed, sterile cartridges for safe handling
• Durable plastic housing minimizes gaps and friction points
• Designed to work with standard cartridge-capable rotary and pen machines
