INCLUDES 1 RANDOM COLOR BALL - This is a very fun stress toy that is not only calming, but it also helps build hand and finger muscles and bilateral coordination. It is a jumbo ball that is filled with doh which makes it a large moldable stress ball. The ball is 4" when it is round, but can be stretched out! This is very calming because it has a very silky soft feel, and you can pull and indent it multiple ways. I like it because you can turn it and pinch it just like you did in elementary school when you made pinch pots with clay. You need to feel it to really know how nice these are. Fidgets are a self-regulation tool used with children who have a difficult time sitting still or focusing. Fidgets help promote focus and concentration, and keep the body (fingers) busy so they can still sit and focus! Fidget toys are also great for strengthening hand muscles and building fine motor and finger dexterity.
