Kwadron Classic Round Shaders
Kwadron Classic Round Shaders are traditional on-bar tattoo needles (RSLT) made for shading and colour packing once the outline is complete. The needles are grouped along the circumference of a circle, parallel to each other, which gives even ink saturation and consistent coverage. A dependable choice for professional tattoo artists who work with on-bar needles, tubes and grips.
What you get
- RSLT — Round Shader Long Taper
- Needle diameter: 0.35 mm (#12). In the variant name (0.35 LT), 0.35 is the diameter in mm and LT stands for Long Taper
- Groupings of 7, 9 or 11 needles (Kwadron references 1207 RSLT, 1209 RSLT and 1211 RSLT)
- Stainless steel, EO gas sterilized
- Box of 50 needles
Artists typically reach for a 7-needle round shader for tight shading and small fills, then move up to 9 or 11 needles for larger areas, soft gradients and solid colour. Many prefer a long taper for smooth shading and gradual colour build-up. Round shaders are commonly used alongside round liners of the same diameter, so you can outline and shade with a consistent gauge. Mount them on your usual tube and grip for on-bar work.
