Our non-adhesive nipple coversare petal-shaped with tapered edges. They provide exceptional coverage with a smooth look & feel that's virtually invisible under clothing. The 4 inch wide, contoured shape is meant to slip into any form fitting bra, bralette, swimsuit or sports bra to conceal nipple projection. The high quality silicone is glue-free,naturally hypoallergenic and safe for all skin types. Best of all, the non-stick design allows them to be washed and reused over and over again. Our non-adhesive nipple covers have a "matte finish", so they will not shine or reflect light from camera flash. Perfect for all breast shapes and sizes.
