This set contains: 4 x Mini makeup sponges Beautyblender® features an open cell structure that fills with small amounts of water when wet. This allows the sponge to be "full" so that the makeup product sits on top of the sponge rather than being absorbed, allowing you to use less product every time. When wet, beautyblender doubles in size and becomes even softer, returning to its original size when it air dries. Beautyblender has chosen to use safe, water-soluble dyes that do not harm the environment and will maintain the integrity of their proprietary foam. For this reason, you may notice some color run off or wash away the first time you wet beautyblender. This is normal and will disappear after you have cleansed the product several times. Please note: the color will not transfer onto the face or clothing.
