Celebrating our 10th year in business, we are the ORIGINAL FIDGET COMPANY, don't be fooled by imitators and copies! This listing is for the Rizzle, the ultimate ADDult Fidget! Not only does this fidget reduce stress, anxiety and symptoms associated with ADD/ADHD it increases focus and attention! Each Rizzle has 2 interlocking rings with 8 aluminum rollers to create the fastest and smoothest fidgeting experience. Rizzle was desinged for adults becuase it's larger than our other fidgets, but can be used by kids too.
