These magnets are awesome! When you have a column 20 magnets long, it wants to stick to everything! However, if you seperate the magnets and let them come together themselves, there is a chance that a few will break or chip.

Exactly what I was looking for at a great price. Arrived on time Thank you

Extremely pleased with these magnets. They were the perfect size for my project with plenty of holding power.

Excellent service.

I have some magnetic white boards with some markers which came with weak magnets attached and erasers with weak magnets inside. When I moved the boards, the markers and erasers would easily fall off. So, I got these neodymium disc magnets. I just attach some to the white board and then attach the markers to them. I opened the erasers and replaced their magnets with these. Hurray! No more falling off! This size is perfect for the markers. Can't see them underneath when the marker is attached. The erasers came with larger diameter magnets, but these smaller diameter magnets work great - didn't need to go bigger.
They come stacked with spacers in between. They are strong, but I was able to slide them apart sideways with no problems. CMS is my go to place for magnets, if I ever need any again. Cheaper than Amazon even with CMS shipping.

Great product and great company! Found the same product for a similar price on other sites but the shipping was outrageous. Very reasonable shipping costs here. If I ever need another magnet I'll definitely be back!

They are fun to play with, but use one as a fridge magnet and have even more fun trying to get it back off.
I've had magnets like these in the past, and these seem to exceed the strength of those.
A couple rubs on a screwdriver shaft and it is magnetized maybe to the point of being annoying.
So yes, very strong, nice size, and I expect they will find uses other than what I bought them for.

Outstandingly powerful for such a small magnet.

Works great!
