Philips Avent SCF153/03 Nipple shields help you to breastfeed longer by protecting sore or cracked nipples during breastfeeding. Made of ultra-fine, soft, odorless, taste-free silicone, the nipple protectors let you keep nursing comfortably. The silicone shield covers your nipples so your skin can heal, and baby's latch-on creates a seal, letting your little one suckle milk through the shield's holes. The shields are narrow, so baby's nose and chin to touch for maximum skin contact while feeding. Soft thin silicone material fits securely to your nipple and is designed for easy latch on. The case can be used for storage or travel. Includes: 2 medium size nipple shields and a storage case
