SALON de Dolce black makeup brush set of 3 and 4 bonus brushes. I don't know the material of the bristles. I think it's good for event makeup like Halloween (^◇^) I bought it a few years ago, but I haven't used it much and have stored it with other makeup tools. The bristles seem to be in good condition, but the characters on the handles are rubbed off on some. The bonus brushes have deterioration on the surface of the metal parts. If you don't need them, please send a message when you purchase. Since it is a long-term storage item, we recommend washing it before use. If anyone would like to use it, please. * Simple packaging with recycled materials, and it will be sent by post.
