MIN CI 20Pcs Powerful Neodymium Disc Magnets,15 x 2mm Strong Rare Earth Magnets Heavy Duty, Small Round Magnets for Refrigerator DIY Scientific Models Office Industrial Tiny Magnet

I've purchased "neodymium" magent in the past and have been very unsatisfied! Not actually the materials as described. These are The Real Things"! Real Neodymium "coin" magnets. I use them for various applications: I fly a flag 9n my porch railing, a few of these placed on the bottom corner keeps the flag from flapping out of control into my vines and structure which causes damages. One Very Important Point: please, PLEASE take care when placing these very strong magnets into a box or container... they Are Very Strong, if left to "attract" against another or other metal/ stone/ gard, durable material -- THEY CAN SHATTER!NEVER EVER place one on one side of your body with another onto opposing side! NEVER leave in a small child or unresponsable person, they ARE NOT TOYS ON THEIR OWN!If they suddenly slam into each other they can shatter, leaving sharp pieces, causing injury! We Don't want/ need that!I'll also be using these to attach various items onto my steel refrigerator doors for quick, easy access.Again: Not A Toy!

right item, right price. Great magnets

These are definietly powerful. I wanted to hang some small tin signs from the metal walls of my shop and these are working well for that. And, they are smaller than I expected. They are actually more like 19x2mm rather than 20x3mm, but even with that minor difference I didn't quite grasp just how small "20mm" really is. For US folks, it's right at 3/4". Much more like a nickle than a quarter.

These magnets are very strong and will jump across a distance toward each other. One hit its mate so hard that it shattered.

I like them because they're small used them on the fridge holding small cards no mess like the big ugly ones

My package arrived with three of them broken. And believe me, it was pretty damn hard to get some of those little tiny pieces off without cutting through a piece of fabric I was holding, but they are very strong.

For some reason, things in the trunk of my car are put together with breakable plastic, and in one instance, rely on magnets to hold a part in place. And those magnets had disappeared somewhere beneath the spare tire. I first ordered another type, little, round black magnets, that proved very inadequate for the task. So I returned them to Amazon and ordered these Neodymium Disc Magnets. Talk about holding power. They came in a short tower of round magnets, in a nice little box. They were so strong that the only way I could extract just one from the top of that tower was to slide it to the side and then get some leverage. to pry it off. FYI, the description mentions "double sided adhesive." I wasn't looking for this, and Super Glued my new magnets into place. It was later that I discovered that a bunch of 3M adhesive rounds were tucked away beneath some of the packaging. I didn't need them-- but if you are looking for yours, check under the packaging material.

There weren't any adhesive tabs included with the magnets kind of defeated the purpose of what I needed them for. The Magnets are very strong as stated by the company.
