Volport Metal Mounting Plates/ Black face/ Adhesive stick up back. 10 plates; small circle, larger circle, rectangle. Thin film plastic to stick on front face so magnets don't scratch black surface. (These are metal plates %26 a magnet will stick to them but they are not themselves magnetic.) **These are apparently designed to use with some phones that need such stick on plates but I just needed a metal surface to which to attach a soda pop tab puller with magnet on the back. I was attaching it to a mesh metal pencil cup but it kept getting lost. **I stuck a small circle metal plate to my printer %26 then the soda tab puller to the metal plate. Easy access %26 it does not get lost. Works great. **I can see the stick up metal plates being used to establish a metal surface anywhere you need to stick up a light item with a magnet on it or which is itself magnetized. **Adhesive on back is 3M but it not designed to be removed, It is permanent so consider that before attaching to furniture.
