Strong Ceramic Round Adhesive Magnets, 0.7x0.12 (18x3mm), 50 Pcs

I’ve been using them with cold porcelain clay. It’s going great. I love these. Strong magnets with strong adhesive, I haven’t had any pop off my clay pieces yet and they hold up thick somewhat heavy pieces well

So I designed this marker holder and 3D printed it, because our other one was crap, and I wanted to use a good magnet on the back side to hold it on the fridge. The adhesive sticks very well to PLA Filament. It's a very strong magnet on the fridge as well. I used four magnets to hold it up but I honestly could have gotten away with two. They are pretty strong. I also cleaned the PLA to make sure the adhesive side would stay on. Overall 5 stars. Exactly what I needed. They're pretty close to the size of a quarter.

Very nice quality and strong magnets! I would give these more stars if possible. The sticky bit is good as well and they hold a good bit of weight. There are no sharp edges. They seem to be well made!

These magnets do a good job on my refrigerator, but the glue attached was less successful. My intended use was to attach to recycled plastic bottles to make magnetic spice jars. Sadly, the glue will not stick to plastic, so I had to physically remove this glue "strip" and attach with a "hot glue gun" instead. Still, when used on other surfaces, such as metal or cardboard, the glue seems to work well. The price point is acceptable, if not good for how well these work.

Great magnets with strong adhesive. 1" rounds, strong enough to hold spice jars securely to a steel plate. Very pleased with this purchase.

If you expect these to hold up a socket wrench set, you'll be disappointed. But if you take them for what they actually are—compact ceramic discs for lightweight utility—they get the job done nicely. The Build & Strength The Pull: These are standard ceramic ferrite discs, not rare-earth neodymium. They have a predictable, gentle pull. Perfect for sticking lightweight puck lights under a cabinet, securing small plastic sensor hubs, or hanging light craft pieces. Stacking Trick: If you need a more decisive "snap," group two or three together. Doubling them up adds noticeable holding power without adding much bulk. The "Manual Truth" (What They Don't Tell You) The 24-Hour Rule: The backing uses red-liner 3M tape. Here’s the catch: do not stick these to a surface and immediately snap the magnet to metal. If you do, the magnetic pull will yank the fresh adhesive right off before it cures. Clean both surfaces with rubbing alcohol, press firmly, and let that adhesive sit for a full 24 hours before you introduce any magnetic load. The Verdict Reliable, clean, and plenty strong for featherweight projects around the shop or house—as long as you respect the tape's curing time.

I'll give them 3 stars but I'm being generous. They're not very strong. I had to use four of them to ensure that an undercabinet LED puck, 4 0z of plastic, would stay reasonably secure hanging from a metal plate. I mean, I do wish they were stronger... but they are easy to install. I'll keep them because it's too much of a hassle to return them and I figure I can find places to use them. And they are easy to install.

I used these magnets to hold up my felt lettering for my babyshower backdrop. It worked out perfectly! Recommend this hack. The magnetics sre durable and good quality.

magneti e biadesivo molto potente! consigliato.

Me ha gustado la diadema muy cómoda y el sonido es algo metálico pero por ese precio y para lo que los quiero está muy bien

I bought these to make up some visuals for my autistic kids. They work really well. Almost too well for the purpose 😅 Fast post. Thanks

These are great. They are strong and work for what I need them for. I bought them for my shower curtain to prevent water on the floor. You get lots of magnets and they have stickers. The only thing is I wish there was stickers for you to apply yourself because they are sometimes on the wrong side for the magnets to work. So I had to use tape which looks hideous but oh well I can make it pretty later I just wanted to see if this would work and it did :) no more water

Absolutely brilliant magnets. I got these along with another set to see which would work best. The others were disappointing but these! These are perfect! They’ve got real nice adhesion, easy to use and they’ve got some really good strength to them! Definitely recommend as they work great for magnet making.
