Not satisfied with the standard medical type pin wheels, "Scott Paul" has designed the original "Double Trouble Pin Wheel" specifically for play. The "Double Trouble" has two wheels for added sensation. It's both a statement of style and fear. These pin wheels are made of stainless steel. They are set one inch apart and are very sharp. The handle is five inches long and covered with easy-to-grip mesh webbing. The entire unit is bleach safe, and conductive for electrical play. Packaged in a clear travel tube for safe storage. Pick your favorite color, black or white.
