KWADRON Cartridge — Round Liner #12 (0.35mm) Long Taper (20pcs/box)

The KWADRON Cartridge System pairs ultra-sharp surgical stainless steel needles with a medical-grade housing and KWADRON's needle stabilization system, which keeps the grouping stiff, focused, and precise while minimizing friction inside the tip so needles stay sharp through the session. The carefully engineered tips maximize precision, control, and ink-flow visibility, and the snap-in attachment allows quick cartridge changes mid-session. Fits standard cartridge grips and rotary/pen machines. Sterile, single-use, 20 per box.

Round Liner Long Taper (RLLT) groupings arrange needles in a tight circle centered on a point for perfectly sharp lines and fine detail — from thin single-pass lines to bold outlines.

Long taper needles narrow to their point more gradually, depositing ink more slowly and precisely for finer lines, smoother soft shading, and gentler pigment saturation with less skin trauma. #12 (0.35 mm) standard-gauge needles deliver faster ink flow for bold lines and solid color packing.

Available groupings (20 cartridges per box):

• 5 needles — SKU CK550-5
• 7 needles — SKU CK550-7

KWADRON needles and cartridges are made in Krakow, Poland and are among the most trusted in professional tattooing — surgical 316L stainless steel, lead-free silver-bearing solder, and rigorous per-product quality testing.
