Non-toxic and baby-safe, this set of 3 teething keys is made of 100% natural bamboo. The chunky design fits perfectly in a baby's little hands and mouth. The keys come in a set of three, so there is always one in grabbing distance. Featuring clever phrases like “key to my new crib” and "Key to my mom's heart." keys are packaged in a tray that also doubles as baby's first puzzle.
