The product includes 40 pairs of round nipple covers, each with a diameter of 2.36 inches. Made from ultra-thin non-woven fabric, they are lightweight and breathable, blending seamlessly with your skin tone without reflecting or showing through. The adhesive sticks closely to your skin, with a soft, glue-free center that ensures stable adhesion without slipping, effectively preventing any embarrassing shifts. The skin tone design provides an invisible look, suitable for various sheer clothing items like backless dresses, tank tops, swimsuits, and T-shirts. To ensure gentle removal, dampen the covers with water before taking them off to avoid discomfort from pulling on the skin. With 40 pairs in a pack, this set provides a long-lasting supply for everyday wear, whether for work, dates, or last-minute outfits.
