Squeeze Toy 5-Piece Set Soccer Ball x 1 Baseball x 1 Yellow Ball x 1 Net-Filled Ball x 2 The net-filled balls are mysterious objects that you can squeeze and squish. When you squeeze them, the little beads inside pop out from all over, and they return to their original shape when you release them. I think they're good for relieving stress. I also think they're good for people undergoing rehabilitation, such as those with paralysis. I have stored them unused. If you understand that they have been stored at home, I would appreciate it.
