Lot of 4 Nanodots Gyro Duo Desk Toy

I once collected all things magnets nano. Included but mostly Zen magnets. I bought these because of that addiction. I just never got into playing with them because I was more into the 5 mm Spears. However, this is a very cool toy and you will not find any more of these available anywhere. At least I can't. They are in like brand new condition. Please let me know if you have any questions.About this productIt's time to upgrade your desktop with this magnetic kit of playful magnets by designer Tim Szeto. Each Nanodot GYRO features an internal mechanism that holds a set of four high-powered Neodymium-Iron-Boron magnets. The mechanism decouples the motion of the magnets from the GYRO’s surface so that the GYROs can function like excellent spherical gears. The transparent housing lets you see the internal mechanics of how they react to magnetic fields, objects and other GYROs up to 12 inches away. This set includes two additional magnetic proxies so you can experiment away. Perfect for everyday use. superior materials and excellent craftsmanship ensure long-lasting durability.
