The Magformers Basic Plus 30 set includes new magnetic shapes like circles and squares with circle insides, adding creativity to your 3D structures. The set contains 4 circles, 4 squares with circle inners, 12 squares, and 10 triangles with strong magnets safely sealed in every piece. Because the magnets freely rotate, they always connect and never repel when two pieces are brought together. An idea booklet to help you design and build different building, vehicles and objects is included.
