The Silicone Nippless Covers are made of skin-friendly, soft silicone with an adhesive layer on the inside to easily apply the covers on the nipples. The nipple covers are made with ultra thin edges and can be worn with or without a bra. They are invisible under clothes. Simply rinse the covers briefly with water and the covers are ready to be worn again. Available in 2 sizes, the covers are suitable for larger breasts/nipples.
