Great quality, handle with care
These magnets are very powerful. They snapped together quickly when I opened the package, so be careful not to pinch your fingers. Perfect for organizing tools in my garage.

Best magnets I've owned
I've tried several brands, and these neodymium pads are by far the strongest. They hold my large dry-erase calendar sheets perfectly in place without any sagging.

Excellent value pack
You get a good number of magnets in this pack. The nickel coating looks premium and hasn't chipped even after months of daily use on our kitchen fridge.

Perfect for DIY projects
Used these to make magnetic closures for leather pouches. They are strong enough to keep the flap secure but thin enough not to add bulk. Highly recommend for crafters.

Strong but slippery
The magnetic strength is undeniable, but the smooth surface makes them slide off vertical surfaces if the item being held is slightly heavy. Good for light papers, less so for heavy photos.

Incredibly strong for their size
I bought these for my classroom whiteboard and they hold up thick laminated cards without slipping. The magnetic pull is impressive considering how small and sleek they look.
Q: Can these be used outdoors in the rain?
A: While the nickel coating offers some protection, prolonged exposure to moisture can cause corrosion over time. For outdoor use, we suggest applying an additional waterproof sealant.
Q: Are these magnets safe to use around credit cards or hard drives?
A: Due to their high strength, we recommend keeping these magnets at least 6 inches away from credit cards, pacemakers, and electronic storage devices to prevent data loss or interference.
Q: What is the actual holding weight on a vertical steel surface?
A: On a thick, flat steel surface, each magnet can hold approximately 8 lbs vertically. However, holding capacity decreases significantly on thinner metal or uneven surfaces.
Q: Is there a bulk discount for ordering more than 10 packs?
A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly through the 'Contact Seller' button for a custom quote on large quantities.
Q: Do these come with adhesive backing?
A: No, these are bare magnetic pads without adhesive. If you need to attach them to non-magnetic surfaces, you can easily glue them using a strong epoxy or super glue.
