Robocik, you have many circles; these are not wheels, they are teeth that you can turn at will. It really doesn't hurt; they spin around nicely, which is a lot of fun. Robot Jojo comes with 5 wheels that should be fitted into the corresponding holes so that several can work at the same time. This game teaches logical thinking, hand-eye coordination, and patience. If you have a shoelace, the shoelaces can be selected separately. Dimensions: 24 x 24 cm + 5 gears. The toy is packaged in a cardboard suit with snap fasteners. Recommended for children aged 3 and up. CE, EN71, FSC®.
