Keychain for keys, backpack, bag, or pencil case in three particularly friendly designs: teddy bear, unicorn, and cat. Simply fill the wooden charms with colorful foam clay: green, orange, blue, and purple, and wait for them to dry to create a unique decoration. Finally, pass the metal chain through the hole in the charm and hang it on your keys or bag. Decorating the charms develops fine motor skills and creativity, while also exercising the ability to concentrate.
