Nuby’s IcyBite Keys Teether Toy is the cool way to soothe teething pain. This clever cooling teether uses purICE gel to help soothe tender gums. The teether's purICE gel filling stays cooler longer than water-filled teethers, providing extended relief for sensitive gums. Pop the IcyBite Keys in the fridge to chill out, then let your little one nibble and teethe their way to relief. For additional soothing, the teether's multi-textured surfaces massage and stimulate baby’s sore gums. The keyring design is easy for little hands to grasp and hold, which supports tactile development. The IcyBite Keys feature bright colors to draw little eyes and keep baby’s attention. Nuby’s IcyBite Keys Teether Toy is BPA-free and made to last.
