Are you ready for a pastime you won't be able to put down? The TetraMag is made of 216 small, but very powerful, magnetic balls. You can create flat or 3 dimensional structures, sculptures, spheres, pyramids, you can stick them to your fridge or invent a new game! Or you can try rebuild the cube you found when you opened the box the first time! It's not that easy! Your imagination is the only limit. With a TetraMag in your pocket you will not know what boredom is anymore!
