Material & Size: Made from anti-drop ABS material. The rotating cube-shaped magic cube ball has a diameter of 5.3cm (2.5 inches). How it Works: Features 4 carefully designed O-shaped concave holes. Each groove contains several small beads that move and rotate by pressing the center module. The small beads move and rotate, mixing different bead colors. The challenge is to match the colors of the balls and holes. 360-Degree Rotation: Grip the top and bottom two snaps with your fingers, press the sphere, and rotate 360 degrees. It can be used as a rotating decompression ball, offering fun and stress relief. One sphere, two ways to play. Creative Decompression: This puzzle fingertip game helps children develop hand-eye coordination, grip strength, spatial reasoning, and logical thinking. Great Gift: An excellent choice for birthday party bags, Christmas, New Year, classroom rewards, carnivals, prize boxes, and candy bag fillers.
