Review on Enhance Your Kitchen with LOVIMAG Neodymium Countersunk Adhesive Refrigerator Magnets! by Tay Fair

WARNING --- Keep this and all magnets out of the reach of children. You can trap the child and cause injury. Adults don't believe me? To attempt. WORSE, if a child swallows two small rare earth magnets, the magnets are strong enough to stick together through the intestinal wall. Get the picture clear? I'm not joking. I'm not involved in any of these industries (I work for the federal government). If you are wondering if they can hold a hammer, knife, tools, car keys etc etc. Yes you can. No, you can't use them to lift a car and I can't tell you the exact weight they can carry, but for such a small size it's a serious amount. You really have to pull to remove the middle hammer from it. Lay the magnet flat on a metal surface and you can pry it off, but it's very difficult. You have to move it. How long does the magnet stay strong? They claim years but I can't confirm it. I can say they hold their power MONTHS longer than anything I've seen.
