These 2 sets of Geomag allow you both to create movement and feel this movement. In general, we bought these sets not because we love spinning tops this much, but because we wanted to add pentagonal plates and multi-colored rods to the pieces we already had. Of course, it was also interesting to play with tops. In the end, we both played and added pieces to other sets. The children liked it. The smaller set is designed for spinning on the surface, the larger set, in yellow-green colors, is designed for spinning in 3D space.
