Description *Develops fine motor skills and cognitive abilities! During toddlerhood, activities that use the hands are so important. The Tok Tok First Puzzle Book series helps children build finger strength and precise manipulation skills as they pop puzzle pieces out and fit them back in, supporting fine motor development and improving hand-eye coordination. Children also learn animal names in both Korean and English, and role-play with the puzzle pieces to boost cognitive skills, language development, and social skills. *Boosts concentration and a sense of accomplishment! When your child pushes a finger into the round hole on the back of the page and pops out a puzzle piece with a satisfying "tok," they build finger strength and focus with every piece. And as they fit each puzzle piece into place, they experience a wonderful sense of achievement. *Safety comes first! The Tok Tok First Puzzle Book was designed with your child's safety as the top priority. It has passed all hazard tests specified under the Special Act on Safety Control of Children's Products and has received KC certification. Enjoy playtime together with a product whose safety has been thoroughly verified.
