POP IT FIDGET TOY ROUND SMALL Size: 12 cm Round Great Pop Fidget Toys for All Ages! Great Pop Fidget games for all ages! ► Fidget toys are based on the theory that children seek objects to grasp and feel, thus receiving sufficient sensory stimulation to relax their nervous system. Fidget toys are often used to input stimuli in a non-disturbing way for others. They can help concentration and attention by letting the brain filter out unnecessary sensory information it receives from the environment and the body itself. By targeting the tactile system, the hands can become very good regulators of concentration and attention.
