2 pair (1 black + 1 nude) adhesive breast lift nipple cover provide a strapless and backless lifting effect, making them ideal for low-cut, halter, or sheer outfits. Most are made from medical-grade silicone that is hypoallergenic and skin-friendly.The circular base covers the nipple, while the elongated "ears" are pulled upward and adhered to the skin to create an instant lift. They are typically washable and reusable. After each use, they should be hand-washed with mild soap and water, then air-dried before re-applying the plastic protective film.
