How to check the quality of semi cream?
Apply the pigment on the hand back.
Rub it back and forth with your finger surface.
The more delicate and smooth, the better quality. Check whether the color is pure visually.
Put one drop of pigment on white paper.
Scribble with a cotton swab to check the purity of color.
