Extendable Breathing Ball

The ball is made of high-quality PE plastic, which is durable. This product does not need to be installed and can be used directly. If you throw the ball out, the ball will of course become bigger. If the ball falls to the ground or hits an object, it will automatically shrink and become smaller. This kind of fun is endless.
