Spinner toys, often known as fidget spinners, are small, handheld devices designed to spin around a central axis. They typically consist of a bearing in the center and two or more prongs that extend outward. These toys gained popularity in the mid-2010s, marketed as tools to help reduce stress and improve focus for both children and adults. Fidget spinners come in various shapes, sizes, and materials, including plastic, metal, and even wood. While some users find them helpful for managing anxiety or improving concentration, others simply enjoy them for their entertaining spinning motion. The rise of spinner toys has also led to the creation of numerous variations and designs.
