Great value for the price

Compared to other magnetic mounts, these offer superior strength. The circular design looks clean and unobtrusive. Highly recommend for organizing metal tools in the garage too.

Holds my cast iron pan lid!

I needed something to hold a heavy cast iron lid on the side of my refrigerator, and these worked perfectly. I used two pads just to be safe, and it hasn't budged in three months.

Strong hold, but permanent

These magnets are very powerful. Just be aware that the adhesive is meant to be permanent. Once you stick it to your fridge, removing it might leave some residue or require effort. Great for heavy items though.

Perfect for my classroom whiteboard

I bought these to hold up teaching aids and flashcards in my elementary classroom. They are incredibly strong and haven't fallen off once, even with kids bumping into the board. The 3M adhesive is top-notch.

Exactly as described

Heavy-duty is an understatement. These neodymium cores are serious. I use them for a DIY project mounting sensors on my car hood (for static display only), and they work flawlessly.

Good magnet, tricky application

The magnetic strength is excellent, but applying them straight was a bit difficult because the adhesive grabs instantly. Make sure you align it perfectly before pressing down.

5 FAQ

Q: What is the maximum weight one pad can hold vertically?

A: On a clean, smooth steel surface like a refrigerator, a single pad can typically hold up to 1.5 lbs vertically. For heavier items, we recommend using multiple pads to distribute the weight.

Q: Do these come in different sizes?

A: This specific listing is for the 25mm circular pads. We do offer other sizes in separate product listings if you need larger or smaller diameters for your project.

Q: Are these safe to use near credit cards or electronics?

A: These contain strong neodymium magnets. Please keep them away from credit cards, hard drives, pacemakers, and other sensitive electronic devices to prevent data loss or interference.

Q: Will these work on a painted drywall surface?

A: No, these magnets require a ferromagnetic surface (like steel or iron) to hold objects. They will stick to the wall via the adhesive, but they will not provide magnetic holding power on drywall.

Q: Can these be removed and reused on a different surface?

A: While the magnet itself is reusable, the 3M adhesive backing is designed for permanent installation. Removing it will likely compromise the stickiness, so we recommend using new pads for new locations.
