DIYMAG Ceramic Round Magnets for Crafts 200 Packs with Adhesive Backing. 0.7Inch (18mm) Small Magnets Perfect for Fridge, DIY, Building, Scientific, Craft, and Office.（0.7 * 0.12Inch-200p）

I use these frequently in both my senior dementia group and my pre K class. The magnets are very strong and I have never had one break. It does require a strong glue or just taking it off the fridge will peel off your project. Super nice quality.

Great adhesives. SUPER strong magnets. They were thinner than I wanted (my mistake) but they hold like their touching the surface.

I hot glued these onto the back of fake flowers to use for the side of a truck. They held up fairly well, a few magnets wouldn't stick but I re-glued new ones from the same pack and they worked! They held up all day which I was impressed with. I was expecting a little bit of a stronger hold but still overall not bad!

-Easy to "assemble" - just peel the sticker and attach a magnet to the double sided tape dots and you're good to go-The double sided tape dots are very sticky and hold well. I've had no problems with glossy paper, thin ceramics, enamel pins, or small wooden canvases falling off after 9 months of use-Great for converting stickers, photos, enamel pins, etc. into magnets-Only potential drawback is that the double sided tape dots may peel off their sticker paper by themselves if you don't store them properly. Keep the papers straight and avoid stacking things on top that may cause friction

These worked well for making my refrigerator magnets. They were a bit smaller than the Hobby Lobby brand, but in the long run, the size was better. They are pretty strong. Don't get them close together or they find each other quickly.

The smell made me want to vomit for nearly 10 minutes afterwards. Seriously, I’m a wife and mother of two toddlers who grew up with three brothers. I have smelled some foul things in my life. I cannot even comprehend how this item doesn’t include some form of carcinogen or toxin. I kid you not, it was a mixture of paint thinner and oddly enough bad breath? I didn’t necessarily feel sick immediately either. When I opened it, I was like what the heck is that smell? I took out the 3m stickers and took a whiff and immediately had regrets. I thought well maybe it’ll fade, let’s see if they will work. Well they stick to each other and not metal, so also useless for what I bought them to do. I had planned to use them to hold one of my cats metal food pans down so the other cat would stop dragging it out from the feeder. Doesn’t do it to his own just to my other cats. But, I digress. I put it back in the box with the plans to return it and WHAM, my stomach starts cramping up and I start feeling like I’m going to heave. It doesn’t let up for a solid 8-10 minutes. Like seriously?! I rarely feeling like puking, I don’t have a weak stomach by any means. You could discuss a gross dissection of something and I could still eat through it and I didn’t even have morning sickness with any of my pregnancies. If my examples can give you any indicator of how dead serious I am right now. Nope, just nope. I might’ve taken a video to help with tho the verification of the magnetisms, but it is not worth the risk of feeling sick again.

These are NOT rare earth magnets - they are ceramic (I think). They are not very strong, but worked for my application for lightweight fridge magnets. If you need a lot of holding power, move along - there's nothing for you, here.

These circular appx 1 inch to 1 1/2 inch smallish magnets have been perfect for a metal sign I wanted to attach to my front door. They have a strong (surprisingly strong) magnetic hold and the metal sign is very securely attached to my front door now. They are very handy, helpful, good quality thickness, power, easy to remove if need be and hold great versatility for many uses. I highly recommend.
