The brightly coloured orange, red and natural blocks of the Haba 3D Arranging Rubius allow an amazing variety of patterns and shapes to be formed. And that's not all. These three dimensional blocks can be fitted together to create small structures in ever growing variations. The set includes 16 blocks and a template booklet so whether your child plays by themselves or with friends, there are no limits to what their imaginations can produce. The geometric forms develop spatial imagination and fine motor skills through the medium of play. Made in Germany from beech wood, they can be combined with the 3D Arranging Viridis for countless variations and effects.
