Finally available; the Rainbow Neoballs set. We heard your requests and have delivered. A perfect way to add color to your magnet collection, or start a magnet collection for that matter. Inside is 36 magnets of each color; Yellow, Orange, Red, Purple, Blue, and Green Neoballs.

This magnet set is screaming for your creativity and innovation. There are plenty of fun color combos to work with and discover. Be sure to check out the Gallery for inspiration on colorful builds! The best part is that their colors won’t fade with normal use! Please don’t subject these little things to hard impacts or fast speeds-- that’s just not what they’re built for. If used gently like the precious gems they are, the coating can last for years.

All Polymer Neoballs feature a ± 0.05mm tolerance, meaning that due to manufacturing differences between spheres, Neoballs and those who love them can count on a variation in diameter of at most 0.05mm. Don’t worry, you won’t be able to tell. We’re just magnet sculpture nerds who care probably a little too much.

Every set of 216 Rainbow Neoballs includes:

  • 36 Yellow 5mm Neoballs
  • 36 Orange 5mm Neoballs
  • 36 Red 5mm Neoballs
  • 36 Purple 5mm Neoballs
  • 36 Blue 5mm Neoballs
  • 36 Green 5mm Neoballs



Rainbow Corrosive Resistance

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


Rainbow 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.


Rainbow 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.


Rainbow Abrasive Strength

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



Neoballs are premium sculpture magnet spheres by the Zen Magnets Company. 5mm diameter, n35 grade neodymium, all Electroplated Neoballs feature a ± 0.02mm tolerance. We are the last American magnet sphere company, and the only one still fighting for the right to sell High Powered magnet sets in the US. Due to our constant struggle for perfection, colors may vary slightly from batch to batch.

Best balls EVER!!

These magnets have been so fun for my 6 yo son and 4 yo daughter. They enjoy making shapes, jewelry, and obstacle courses. They also like seeing what they are atttacted to. The metal tin they come in is super cute as well. They have become a go to Bday gift for us because so many kids (and adults) enjoy playing with them when they come over. Love this product!

216 Set: Rainbow Neoballs

Coating has limitations depending on use

I purchased sets of silver and purple 5 mm as a gift for my daughter and the purple coating was flaking off within 24 hours of use. The magnetism is really great and they make an awesome building/creative set. But if they are going to get more “play” than “display” then I recommend the balls without color coating. I felt like the description of resistance to abrasion did not in any way match our experience. (I suspect that’s the way it is with all marble and bead magnets... though these are the first we’ve tried.)
