"Breast covers are made of silicone that cover the nipples and are not visible under clothing. First, attach the cover to your chest, then lift the breast and attach the upper part of your body to tighten and lift the chest in a more beautiful way. Skin-friendly silicone holds the cover in place. Easy to stick and remove. Care for covers after wearing by washing them in warm water and letting them air dry. Then stick the transparent protective part on the covers to use again"
