The cubes are big, a bit too much for small hands. The design is not very nice, not very attractive, even if he seems to be in the picture. The finishes are very neat (the seams float). The cubes are made of smooth fabric: no material effect that could allow the child to develop tactile skills. A cube contains a bell, which is of no interest in itself if others are dumb (the interest for the child would be to compare the sounds). One side of each cube has a number. However, a small child will play with the cubes will have failed there long when he will address the numbers. Moreover, the fact that the cover contains only six cubes, extend only numbers from 1 to 6, which is of little interest. In short, I am not convinced at all and the childminder who would toy was given no more than me. Sorry.
