These flower shaped nipple covers are made of a unique thin silicone gel on a non-stick moisture-proof membrane. Each nipple cover is self-sticking and adheres to the nipple area to help lubricate and moisturize this delicate skin. It helps reduce dryness and cracking on the nipple surface. Each pad can be worn when not nursing and will not stick to the inside of a bra. Covers are hypoallergenic, washable, reusable and leave no residue on the body. Available in one size only and non-sterile.
