Beautifully weighted, you can spin the sphere using any combination of the round discs or you can use holding in your hand, using your thumb to rotate/stim with a disc in a cyclical motion.
They are a soothing and a beautiful visual stim also.
This is a very fun and actually quite versatile tool. The kids actually enjoy sitting in it on family movie night. It easily fits two of my kids at the same time. They really enjoy the rocking and pressure.
