It is a ring put on the puff. When you normally make up your makeup after skin, eye make-up, and to draw the eyebrows to support the puff. But the puff was not fixed properly. And I can not use the area of the puff properly, and there are things that the back part is swift. So I made a ring to hold the puff. Make-up professionals can use it comfortably, and make-up is also convenient for those who make-up themselves. Use at average puff size. The ring is about 1.8 in diameter, the size can fit your thumb. It is based on the thickness of the fingers of a woman, so you can stretch it to fit your size.
