This is Geomag, a toy my children played with when they were preschoolers. I believe it's a valuable magnetic puzzle that allows children to experience the edges, faces, and vertices of 3D shapes while playing. I also liked that the finished creations were beautiful and colorful, so they didn't look out of place when displayed in the living room. The magnets are quite strong, so the creations are less likely to fall apart, which made it easy to play with. You need a certain amount of pieces to create large works, so we bought two new sets. Please check the details of the contents below and agree before purchasing. I am very sorry, but I expect no claims and no returns. Squares: 49 Triangles: 60 Pentagons: 24 Bars: 116 Spheres: 75 As you can see in the photos, there is a lot of wear and tear, but it comes with the instructions. Price negotiations are welcome.
