Eight cubes with sides of 5cm each. These are building blocks for small carpenters. My child played with them for several months. There are small scratches on the surface, but no noticeable marks or stains. They are 5cm base scale, and I think they can be played with together with building blocks from Naef such as Neuspiel and Ligno, as well as Cuboro. *Please read the profile. #Neuspiel #Cuboro
