I love this item. However, I must warn any parents that it will not be something you want to give to kids or even younger teenagers. They will not be able to resist trying to break it open. They will test it's ability to stretch and squish. The material feels a bit fragile and easy to break/rip/tear. If this happens there will be hundreds of squishy balls all over, for certain to end up in mouths and squished into carpets. It is not particularly durable feeling. It has a tacky outside texture and not filled with water or liquid, it is filled with hundreds of gel beads that roll and squish between your fingers and hand. The outside is thin but feels kind of durable with normal use and I descovered that you can stretch it and kind of bat it like a paddleball against itself. Especially kids who need a product of this type, they will destroy it within minutes. Even though this will probably break, I am going to keep it because breaking will not destroy my furniture with colored pait/gel/dye like the other ones will.
