NIPPLE COVER(ONE TIME USE):Now sport curve-hugging clothes with confidence. Wear sheer blouses without worrying about show-through. Try tube tops, tanks, sports bras, strapless styles, and more...yet still protect your modesty. Just use these disposable covers. Each has non-sensitizing adhesive with a soft, absorbent center. So, it gently molds to your breast shape. And gives you a smooth, discreet look. (Stays on for up to 8 hours.) These covers are waterproof, too, so they're perfect under swimsuits. They even help prevent chafing when you go braless. Hygienic. Not for sensitive skin.
