Neoballs are premium sculpture magnet spheres by the Zen Magnets Company. 5mm diameter, n35 grade neodymium, with colorful Polymer coatings and precise Electroplate coatings. Our goal is to provide you great quality magnet spheres, at extremely aggressive prices, with minimal fluff. High powered magnets are not children’s toys.

A sliding tin container is included with every set. The custom designed and embossed tin is more than an attractive storage case, it also serves as magnetic shielding during transport. Also included with every 216 magnets of a color is a shaped tray for counting and easy removal from the tin.

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.

We have two new additions at popular request.

A solid pearly White is now available, and is not a translucent color like most of the other rainbow colors. The brightness is comparable to a dry erase whiteboard, but the tone is a tinge bluer than neutral.

A Luminous Green glow in the dark color is also available. It’s more expensive to produce, however it’s slightly oversize, so the resulting price is on par with others. Not a strong glow, but noticeable in the dark after a charge.

Dark Blue is actually one of the experimental colors that came from our factory. This is a one time production batch, and will not be continued after sold out.

Corrosive Resistance


Resistance to oxidation, rusting, tarnishing, and moisture erosion.

The new polymer coating is a pseudo plastic overcoat, which is completely different from the typical electroplating process used to coat metal on to magnets, is not susceptible to moisture or oxidation. The polymer technology also offers distinct experience from common electroplated metal coatings. Polymer coating is warmer to initial touch with a softer contact sound.

Abrasive Strength


Strength against rubbing, wiping, brushing and kneading..

Finally, colors that don’t fade with soft abrasion. If used reasonably gently, the coating can last years. The matte texture diffuses reflections, but is still slippery smooth to the touch.

Impact Hardness


Shielding to collision, scraping, hitting and dropping.

It’s stronger and thinner than vehicle paints (which are actually some of the strongest paints around.) But is still soft compared to metal coatings. The polymer coating won’t withstand high speed impacts, or rough kneading.

Geometric Tolerance


Consistency of size and shape matters with structural size.

Conformance of diameter and shape define how well magnets interact with one another. Magnets that are more precisely sized will always lie flatter in a sheet, be more rigid in a frame, and behave more consistent during use. Thus, the larger your sculpture, the higher tolerance magnets you’ll want to use for load bearing structures.

Polymer Neoballs have a diameter of 5mm ± 0.05mm, which are Compatible with the leading competitor’s polymer coated 5mm spheres of the same specifications. Since Electroplated Neoballs are more precise (5mm ± 0.02mm), they are said to be Over-Compatible with lower tolerance magnets. Meaning you can use them together since they are the same average size, but you’ll lose the advantages of the finer tolerance magnets.

Fair Pricing

Our prices will always be very competitive, we’re not here to play games. For honest perspective, our competitor typically sells a set of 125 polymer spheres for $30 (24¢/pc), but discounts for as low as $5 for a set of 125. Neoballs are less than half the retail price of the leading competitor. And while we’re not likely to ever match that way-below-cost promotion of 4¢/pc, you’ll find our prices to be consistently on the low end of the scale and sustainable. Polymer coated Neoballs are guaranteed to be equal in strength, tolerance and longevity to the leading competitor brand of “chromatic” magnet spheres. While electroplated Neoballs are guaranteed to be better or equal than all other brands of 5mm magnet spheres, except the Zen Magnets themselves.

Electroplate Neoballs


216 Gold | $25.92

5±.02(mm) n35 22k Gold

More Info

If molecules were a town, gold would have the happiest electron citizens of the precious metals. Gold does not corrode so all the gold that has been around is still around and will be around. The yellow metal represents hundreds of years of work; mining and refining. Gold is beautiful, however soft.





216 Nickel | $19.44

5±.02(mm) n35 Ni

More Info

This popular coating is the hardest of the electroplated coatings. A mostly colorless chrome coating that is consistent and dependable. Nickel coated neoballs are compatible with other good caliber 5mm magnet spheres such as buckyballs and nanodots. These are not Zen Magnets.





216 Black Ni | $23.76

5±.02(mm) n35 Black Ni

More Info

Black nickel is a sleek decorative coating that offers nothing in additional protection over colorless Ni. Infact the color doped nickel coating kneads off faster on the hands, and will leave discoloration on the skin after much use. The 0.02mm tolerance is common with the colorless Ni coating.





216 Silver | $23.76

5±.02(mm) n35 Sterling

More Info

The specialty of the 93% pure silver coating is it’s brilliant white metallic luster. It is harder than gold, but tarnishes easier. Extremely susceptible to acidic corrosion. A tactile sensation that’s completely unique to silver. All electroplated Neoballs feature a +/-0.02mm tolerance.

2.5±.03(mm) n35 Ni

More Info

For info and full sets, go to: Micromagnets are 2.5mm Neoballs, born out of necessity in the context of CPSC red tape and regulation. Although smaller and weaker, the strength to size ratio allows Micromagnets to form nearly every shape that 5mm magnet spheres can become. Cheaper and more portable, but more difficult.





216 Zen Magnets | ~$45

5±.01(mm) n38 Zen

More Info

Zen Magnets are the highest precision magnet spheres on the market, utterly unmatched. The mirror coating isn’t only beautiful, but its surface is much stronger than mainstream nickel coating and will last twice as long. Only found at For those who require the best.

More Info

These 4mm cube magnets are for people who can’t handle magnets with infinite sides. Six sides is enough to do… not that much. They do look pretty cool sitting on a desk, however. And if you’re looking for something simple to ignite interest in magnets, cube’s aren’t bad. Certainly better than cubes that are not magnets…

These ARE compatible with 4mm Buckycubes, which once sold for 20 cents per cube. For industrial and home improvement applications, these 4mm cubes are an amazing deal.
