Mini Metal Plates for Magnetic Mount, Wall, Phone Holder, Case, Magnet, Crafts, DIY. Kit of 32 Silver Small 0.4" x 0.8" Iron Discs with 3M Adhesive Backing. Steel Replacement Sticker Set 32 Pack

I used these on laser cut signs that had interchangeable components. I have a magnet on the sign itself, but on each interchangeable component, I would put these little metal plates. The adhesive is strong and the material is thick enough that the magnet easy grabs it.

These plates are tiny! They are perfect for adding a metal surface to the newer sewing machines that are mostly made of plastic. It only took two of the little plates to hold a large magnetic guide solidly. With just one plate, the guide wiggled slightly. Since they are so small, they stick well even on the slightly curved sewing machine surface.

Didn't stick to well

Super tiny, perfect to modify my phone case and make it close and stay closed. The adhesive sticker is really good, I stuck it to a silicone case side and it's held up quite firmly, for a good month of about 100+ open/closes in a day. For the quality of these tiny metal plates, you get SO many for such a cheap price!

These have a thin profile and size and were just what I needed to make an area magnetic. They have a 3m adhesive, so I’m confident they will stick!

I use five of them on the back of my phone case

Firstly, these are tiny, self-adhesive metal plates. The self-adhesive side can stick to anything. and it will stick easily and effectively using the two hacks I've described in the video. The metal side is NOT a MAGNET, and metal things will not stick to it. However, magnets can do a good job of hanging on. This is also demonstrated in the attached video. With all that said, these are handy to have around and I'm finding lots of places to use them.

Unable to use because it's badly made. When they stamped/cut the piece, they stamp from the adhesive liner side. On the other (main contact side) the entire edge sticks out! The magnet will not contact with the surface but only on the sharp edge. Only works if your magnet is 9 mm or under diameter, not the 10 mm or larger diameter. The 20 x 10 mm oblong shape and 0.5 mm thickness is correctly described by the vendor. The sharp edge that sticks out will cut you too. Keep some band-aid handy.

Very helpful for using magnetic fixtures on non-stell surfaces. They are small and think so are invisible on deployment.

They are worked perfect for what I needed them for. Adhesion could be better but I used my own super glue. The size is small which is perfect for small magnets. I had to use 9 of them on the back of my phone case to be able to stick my phone to a wireless charging battery pack.

These are handy little metal stickers - they enable you to put a magnet (like a fridge magnet) just about anywhere on almost any surface. I've had no trouble sticking them to anything and they stay put. Not for particularly large objects as the metal is thin, but for small fridge-magnet type things, just perfect.

I bought these to pair with neo magnets to make a sealable curtain on my bedroom window. While the magnets stick, it's not as strong of a bond as I had hoped it would be (even without the fabric between). And I know the magnets work well because you should see me trying to pry them off my fridge haha (that was a lesson learned).

Very easy to install and alteringthe concept very easy.
