These are Edutoy toys from Kodomo Challenge. The Tsumiage Tower is from "Kodomo Challenge Pocket" and is for ages 2 and up. The Animal Balance Puzzle is from "Kodomo Challenge Hop" and is for ages 3 and up. The 3D Rotating Puzzle is from "Kodomo Challenge Jump" and is for ages 5 and up. However, watching my son, it seems like he enjoys all of them regardless of age. Perhaps because he played with these Edutoy toys, he seems to have understood geometry studies smoothly after entering elementary school ^_^ The boxes are damaged, but the contents are in perfect condition, so I hope to pass them on to someone who will enjoy them. These are used items, so please understand.
