Kwadron Tattoo Needle Cartridges — 3 Super Tight Liner Long Taper (3RLLT), Box of 20, Sterile Precision Liners

Kwadron 3 Super Tight Liner Long Taper (3RLLT) cartridges are precision tattoo needles in a box of 20, built for ultra-fine lining and consistent ink flow.

These Kwadron cartridges pair a long taper with a super-tight 3-round liner configuration to deliver crisp, controlled lines and reliable ink delivery. Manufactured with a plastic housing that reduces friction, a full membrane to prevent backflow, and razor-sharp steel needles, they’re engineered for artists who need repeatable performance on detailed work. The box contains 20 sterile cartridges, each intended for single use to support hygiene and consistent results.

How do these cartridges improve line work on detailed pieces?

The long taper and super-tight 3-round grouping focus the needle point for finely controlled penetration and reduced trauma to the skin. This combination helps maintain sharp line edges and steady dot placement during intricate designs.

• Long taper for gradual ink deposit and smoother lines
• Super-tight 3-round grouping for ultra-fine strokes and detail
• Razor-sharp needles to minimize drag and maintain edge definition
• Consistent spacing preserves predictable line weight throughout a session

What features protect my kit and client from ink backflow?

Each cartridge includes a full internal membrane that blocks fluid and ink from migrating into the machine, reducing contamination risk and making cleanup easier. The sealed cartridge system also supports safer single-use workflows.

• Full membrane barrier prevents ink and blood backflow
• Sealed tip design reduces exposure of internal components
• Single-use cartridges lower cross-contamination risk
• Compatible with standard cartridge rotary machines for quick swaps

How does the plastic housing affect performance during long sessions?

The high-quality plastic housing minimizes friction between needle grouping and tip, promoting smoother needle travel and steadier ink flow. Less friction can also reduce wear on the needle and contribute to a more consistent feel over extended use.

• Low-friction plastic housing for smoother needle movement
• Stable needle guide improves accuracy and reduces wobble
• Durable construction maintains alignment across multiple passes
• Lightweight design eases hand fatigue in long sessions
