Pomegranate laugh // Echoes across the oceans // Where it will settle.

  • 864 Red Neoballs (5mm) Magnet Spheres
  • Child Safe Case
  • Quick Build Guide
  • A newfound obsession with something called “redrum”


Stunning like a ruby, deep and dark and luscious like a rose. Red coated Neoballs are not only bright and beautifully colored, they also offer increased longevity, a warmer initial touch and softer contact sound when connected. Red is the color of blood, and the color of the health bar in most video games, so it’s no surprise that these magnets also offer increased longevity over standard magnetic spheres. The red polymer coat on these neodymium magnetic balls truly pops – making them great for giving your sculptures a unique “Christmas-ey” vibe (Or gory, go ahead and add magnet blood to your sculptures. Take pictures of it and submit it to magnetspheres.com! that actually sounds cool.) and can allow you to live out your fantasies of driving a firetruck. A tiny, magnetic firetruck. Made of neodymium balls. One you can drive with your pinky finger.


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.

All Polymer rare earth magnets by Neoballs feature a ± 0.05mm tolerance.


Red Neoball Corrosive Resistance

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


Red 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.


Red 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.


Red Neoball Abrasive Strength

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

Good stuff

Good product and fast delivery. Having fun.

Great product

I was a little skeptical as my son wanted these after watching a video. I figured the real life version wouldn’t work as well but I was pleasantly surprised. My son has been playing for hours and making some great creations!

A great gift

These red neo balls are wonderful in every way, the magnetism is strong, they are resilient to pressure, and have a great coating. Even though I have seen some with not so good coating, you can always send an email to support and they will help you.


Those magnets are very fun to play with and easy to get lost if they get stuck to something magnetic
