Grimm's Rainbow stacker is really versatile and ideal for small children. Toddlers stack, sort and build. As they get older, they will use it as a cradle for dolls, as a fence for animals, as a tunnel or bridge for vehicles, as a house for dwarfs and dollhouse dolls, etc. In short, it will be integrated for years in imaginative play. Materials: lime wood, non-toxic water based color stain. Size: length 17cm in length
