Magneatos from Guidecraft. Magnetic construction set for kids Magneatos has in not only large multi-colored plastic balls with a diameter of 5 cm and magnetic rods 13 and 8 cm long (diameter 3 cm), but also panels. Triangular and square panels are equipped with special holders. And there is the top of magnetic creativity – corrugated tubes that can stretch to the desired distance. The structures are not very stable, since the pull of the magnet and the plastic ball is not strong enough. The stick not always fixes in the right place, unlike in the magnet-metal ball variant. But the idea is good.
