Fidget Spinner: Relieves stress, anxiety, restlessness, useful for developmental disabilities, autism, and ADHD (Attention Deficit Hyperactivity Disorder). Spin can help kill boring time, have fun, improve concentration and deepen thinking. High-speed rotation for 3-6 minutes: The internal bearing of the fidget spinner uses durable, wear-resistant, lubricating R188 stainless steel silent ball bearings, which can rotate for a long time, usually 3-6 minutes. Note: The hand grip part has a detachable nut structure. Long-term rotation and collision during transportation may cause the screws to loosen. Please tighten them before use. Metal material, fine craftsmanship: the fidget spinner has a sense of weight. The main body is made of aluminum alloy, using CNC processing technology and computer-controlled processing, with stable processing quality and high precision. The surface of the hand top is smooth and burr-free, durable, non-toxic and harmless, and very comfortable to the touch. Easy to use: To rotate the ADHD fidget toy, simply hold the sides of the center with your fingers and use the spinner with your other hand. With practice, you can use the spinner with just one hand. To use the anxiety toy on a table, simply press the center to keep it stable and rotate at the same time. Once you let go, the fidget toy will continue to spin. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
