Useful for wrist exercises Screw-turning toy set of 5 (shapes and colors are assorted) Made of plastic Approximate size: 5cm x 4cm This is a "screw-turning toy" that promotes wrist flexibility, which is necessary for adjusting the strength of your hands and fingers, making circles, cracking eggs, and turning faucets. Toys that use fingertips are considered effective in fostering children's concentration and a desire to explore things they like. From the age of 1, children can enjoy twisting and removing the screws, and around the age of 2, they can start to enjoy screwing them in! This toy is recommended for learning about colors and shapes. Please supervise children while they play, as it contains small parts.
