This is great quality product. I have two of them. One for work and home. I find them therapeutic to squeeze and smush and it always goes back to its original shape. They have just the right feel and resistance to them. I’m having hand surgery in a few days and these are going to be perfect for Occupational Therapy/Physical Therapy. I originally bought the small cube, which is still enjoyable and therapeutic (it’s more palm size), but the large cube I can grab and grip with my whole hand and it gets all my fingers involved. Awesome product. Highly recommended.
