A multi-colored maze game, approximately 20cm in diameter. - Product Name: 3D Maze Magical Capsule - Color: Multi-colored - Accessories: Instruction manual - Size: Approximately 20cm diameter Thank you for viewing. My child received this as a reward for effort points from Shinken Zemi. This is a spherical 3D maze where you navigate points from 1 to 100 by rotating it without dropping the balls in numerical order. I think it helps develop concentration. The item has some small scratches from my child using it for a while, but I think it's in relatively good condition. Please understand that this is a used item before purchasing. #KodomoChallenge #Benesse #ShinkenZemi #Maze
