A sugar pressure ball - a super stick and unique restless ball. 2.4 inches - green! This is a very interesting pressure toy that not only calms down, but also helps establish hand and finger muscles as well as bilateral coordination. It is very magical, with a super soft dough feeling. You can poke it, pinch it, and it will maintain its shape, then slowly seep back into a ball, like a slowly rising sticky ball. What does it feel like - super soft cookies or bread in a ball. It's almost like a moving doh, because when you release it, it slowly returns to the sphere. What's inside - very thick transparent adhesive like filling material - the filling material is super sticky and elastic.
