Pyramids

We have added these to our holographic biological signaling and are evaluating. I thought the magnets would be a bit small but they seem fine.
We are using them as one of the drivers for our vortexes.

Exactly what I expected

Good, strong magnets. These are the largest of three sizes I purchased and they are strong!

Great Quality and Diversity

I have a very special use-case for some magnets where the diameter and thickness need to meet strict guidelines while also being strong enough. The quality of the test magnet I purchased was very good, and so I bought more!

Never Disappointed in SuperMagnet Man Magnets

Small, strong magnets like these are my go-to for events. Honestly, I'm surprised that they aren't part of everyone's event kits (among those who have event kits). I can quickly and cleanly attach shirts, hats, bags, signs, and more to canopy legs and cross bars. The wind doesn't stand a chance against magnets when used to hold tablecloths in place. My only complaint is that others do not respect the magnet! They gleefully yank shirts down and let the magnets go flying to disappear in the grass or roll down the street. Magnets deserve more care and respect.
