Nee Doh is available in three sizes: Nice Berg, Nice Cube, Nice Ice Baby.

This product is the medium size (Nice Cube)

1. Not in 3 sizes but in 3 colors, blue, pink, and purple.
2. The dimensions of the cube are about 6 x 6 x 6 cm.
3. I think it's a little bit hard to squeeze for small kids.

6cm x 6 cm x 6cm
