Speks - Original 2.5 mm Magnetic Balls
The original in mashable, smashable fun. Made from rare earth magnets in a rainbow of colors, Speks are quite possibly the best stress-relief desk toy around. Take ‘em wherever you like — they’re the perfect size for work or on-the-go.
WARNING: Keep Away From All Children!
Do not put near or in nose or mouth. Swallowed magnets can pinch and stick together across intestines causing serious injury or death. Seek immediate medical attention if magnets are swallowed or ingested.
