Great for keeping hands and mind busy.

First off no one that uses these have any forms of autism or ADHD. My son does play with it when he has gotten frustrated with something like homework. This fidget cube is made of extra durable non plastic silicon. It has 6 different sides to keep your hands and minds busy. The size of the fidget cube is 1.3 x 1.3 x 1.3 inches. It is small enough to put in your purse or a child's bag when you go on trips, when going to restaurant, making shopping trips or anything that a child or adult may need some help with focusing or distracting their mind.
