Made from rare earth, neodymium magnets, Speks magnetic balls are possibly the most popular desk toy ever made. Speks are like magnetic putty, a stress ball and adult building blocks all in one. Mash them around for oddly satisfying stress relief or build a shape to unleash creativity. Magnet Balls are a fun and educational toy that helps develop problem-solving skills, hand-eye coordination, and creativity. The toy consists of various magnetic balls and rods that can be combined in different ways to create three-dimensional models. Magnet Balls also encourage critical thinking and experimentation, as players can test out various combinations to see what works best. Not only is this toy entertaining, but it also promotes a deeper understanding of magnetism and the physical world.
