KWADRON Cartridge – Round Shader #12 (0.35mm) Medium 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 Shader Medium Taper (RSMT) groupings arrange needles in a looser circle than a liner – the classic choice for shading, color fill and thicker lines. The medium taper narrows to its point faster than a long taper, so ink is deposited more quickly for faster, bolder saturation while still blending smoothly.

#12 (0.35 mm) needles carry more ink per pass than #10, for faster, solid color packing and confident, bold shading.

Available groupings (20 cartridges per box):

• 5 needles – SKU CK604-5
• 7 needles – SKU CK604-7
• 9 needles – SKU CK604-9
• 15 needles – SKU CK604-15
