Ninja Star Fidget Spinners
See more fidget toys here. A fidget spinner is a stress-relieving toy. A basic fidget spinner consists of a bearing in the center of a design made from any of a variety of materials including brass, stainless steel, titanium, copper and plastic. The toy has been advertised as helping people who have trouble focusing or fidgeting (such as those with ADHD, autism, or anxiety) by acting as a release mechanism for nervous energy or stress.
Although they were invented in the 1990s, fidget spinners became a popular toy in 2017.
