NeoFlex® Flexible Neodymium Magnetic Strip - 1 in. Wide

Strongest flexible magnet I’ve ever seen! Seriously. It holds 400g/cm2. For Americans that means 5.6lbs per square inch. Other brands don’t even tell you the strength per area. (But divide strength in half if the load is sheer)However, you must use it correctly. The magnetic side attracts metal well, not other magnets. This it's because it's multipole so you’ll end up with competing poles when you stick it to other magnets. Instead, get some thing steel/iron plates with adhesive backs. Just search for “adhesive metal plate”. I stuck one of these plates to the back of my phone’s case and now I can stick my phone anywhere where that these magnet strips are! I use it for organizing TV remotes, tools, pens, and all sorts of things.The adhesive looks like a real 3M adhesive too. It's very strong. But like all adhesives, make sure you clean the surface first (isopropyl alcohol ideally) and then apply lot of even pressure for 20+ seconds to get the adhesive to bond well. These magnets are actually strong, so you want to take the time to get the adhesive right. You’ll need it!
