Ergonomic EZ Grip design lets babies direct the teether to front or back teeth for targeted sore-gum relief. Made in South Korea from durable TPE, it is BPA-, phthalate-, PVC- and lead-free and meets ASTM F963-17 and CPSIA safety standards. Textured surfaces stimulate tongue, lip, and cheek muscles to support oral motor skills, speech development, and fine motor coordination.
