Princess Castle Blocks Build an amazing Princess Castle with this colourful set of sixty blocks and let your imagination run wild with tales of medieval adventures! Playing with blocks promotes the development of spatial awareness and develops hand-eye coordination as children reach for, lift, move and build with blocks. This is great for strengthening their fingers, hands and arms. Block building improves the problem-solving skills and explores symmetry, sizes, shapes, and other aspects of the objects. It helps a child understand the concepts of cause and effect, balance, as welll as gravity. Not suitable for children under three years old due to small parts, keep out of their reach.
