Kwadron - Optima - 5er Roundshader 0.30 - PT - TX - Box of 20

What is the use of the Kwadron Optima Round Shader 0.30 mm/5PT-T cartridge?

Round Shader needles are characterised by a looser needle placement which results in more pigment being introduced into the skin. While working, they make it easier to build up chiaroscuro and gradation. They work well for powder eyebrows, but where the borders are more blurred, less defined. For contourless lips, blending and shading techniques where blurred results are desired.

KWADRON PMU OPTIMA CARTRIDGES 30/5 RSPT-t cartridges

RS needles are ideal for light, powdery, openwork, less detailed techniques where you want diffused effects. The 0.30mm cartridges will leave a larger pixel than the smaller 0.18mm and 0.20mm cartridges.  

Kwadron PMU Optima 30/5 RSPT-T what's behind the symbols  
These are five 0.30mm needles with a Round Shader type and Point Tapered sharpening step (2.5mm sharpening length) and a textured surface needle, which allows the needle to penetrate more pigment.  

Cartridges designed to create contours and lines and especially fills due to the greater number of needles in the cartridge. The PT taper needle is double sharpened, which means that in addition to the usual sharpening, the tip of the needle itself has been further sharpened at a different, more obtuse angle. This type of sharpening means that the PT needle is not as sharp as the LT, allowing it to be inserted more gently into the skin. PT - Point taper (2.5mm double sharpened).
