Unused brush. I'm not sure what kind of brush it is. I also have many other items for sale or in stock, including cosmetics (Christian Dior, Yves Saint Laurent, Covermark, Bobbi Brown, IPSA, KOSE, Cosme Decorte, Albion, est, SUQQU, Kanebo, wrinkle-improving creams, blemish-improving serums, low-irritant skincare, etc.), unused tableware, and more. Please feel free to comment. I will offer a discount for combined shipping.
