The Comfortchew is made with super-soft jersey cotton and luxurious cuddle fleece, making it super snuggly and highly absorbent. The attached soft textured hippo teether is designed with dimples to massage and soothe tender gums, encouraging new teeth to break through. Tags of various colors and textures stimulate the senses, and the Comfortchew can be attached directly to the baby, car seat, or stroller. Machine washable, BPA and phthalate free, and 100% safe to chew. Exclusively distributed in the US by The Kalencom Corporation.
