Set of 2 spherical magnets with a special surface treatment (approx. 25 mm diameter) Hold the two magnets slightly apart in your hand and throw them upwards. They will fall with a "ziing-ziing" sound. They are also an educational toy that helps you learn about the properties of magnets and magnetism. Small children should use them with caution, as they are dangerous if swallowed. [Condition] There are some areas on the surface where the coating has lost its luster, but this does not affect their use. Please understand that these are used items, and those seeking perfection should refrain from purchasing.
