These Neoballs are akin to playing with perfect emerald spheres. Pair these neodymium magnet balls with a few of our purple magnetic spheres, you can create the state plant of Colorado. Which, of course, is the Rocky Mountain Columbine!


Colors won’t fade with soft abrasion and if used gently, the coating can last for years. The matte texture diffuses reflections, but is still slippery smooth to the touch. The coating is strong & thin, but still soft compared to Electro Neoballs. Polymer coatings are too precious to withstand high speed impacts, or rough kneading.


Sculpting with these neodymium magnetic balls is like being an architect in the Emerald City of Oz, but without living under the totalitarian rule of a fraudulent wizard-king (seriously, read the actual book, it's messed up). What’s not messed up are green magnet spheres from Neoballs – because they’re actually very hard to damage! The coating is strong & thin, second only to Electroplated Neoballs. Green coated neodymium balls are not only bright and grass colored, they also offer increased longevity, a warmer initial touch and softer contact sound when connected. All Polymer neodymium balls feature a ± 0.05mm tolerance.


Green Neoball Corrosive Resistance

Not susceptible to oxidation, rusting, tarnishing, and moisture erosion, this coating is very strong.


Green Neoball Geometric Tolerance

Okay shape and size consistency of magnets. The size variance of these magnets is ± 0.05mm. Currently, this is the tightest tolerance available for this style of magnet.


Green Neoball Impact Hardness

Some shielding to collision, scraping, hitting and dropping. These magnets will not withstand high speed impacts, collisions, or rough kneading without chipping or denting coating.


Green Neoball Abrasive Strength

Very good strength against rubbing, wiping, brushing, and kneading.

Got 'em

All I can say is they arrived quickly. have no given them to grandson yet for Christmas. But they are here so I don't have to worry about them.

Awesome open ended desk toy!

My 9-year old son has been playing with these for two years now and he’s still interested in them! No other object has kept his attention this long!
