The items from Kodomo Challenge are wooden. You can cut food with a satisfying "zack" sound. You can use the rabbit as a puppet to feed things, and it can also be used for storage. The other knives and fruits are made of plastic. These are items I had at home, and I will also include a pouch to store everything. ◎ There are no noticeable stains, but please consider that these are used items before purchasing.
