Every time this pacifier falls, the nipple pops back into its built-in protective silicone bubble. No need for a case. Safe and intuitive with a gentle pop back that mimics the natural teat. Won't pop out of baby's mouth (trust us, #engineering). Minimal washing needed, think just a few times a day. 100% silicone. No lead, PVC, BPA, latex or phthalates. Whenever babe masters motor skills, they can put it in their mouth themselves. Recommended for babies 0 - 1 year Dishwasher safe.
