Half fidget toy, half sculpting tool, entirely magnetic! Speks are the latest in magnetic model-making. Composed of 512 2.5mm rare-earth magnetic balls, these sets can be used to create virtually any shape imaginable. Weave magnetic jewelry, an intricate coil, a hollow cube, or even a fish! Pardoning the clich, the possibilities are as endless as your imagination (and the limits of 512-bead magnetism). When youre finished creating (or havent even started), squish them together & pull them apart for the ultimate stress toy. Comes in a giftable box, complete with a guide, magnet separator, metal base, and a plastic carrying case. A perfect desk toy for young and old alike!
