There are many reasons you’ll want to hang a mirror without drilling or using nails and screws. It could be that the wall isn’t made to support drilling, or you want a hanging solution that is a bit more temporary, which can allow you to quickly take down the mirror.
Command hanging strips are one of the popular products from the Command brand. The company is one of the top makers of adhesive strips that don’t do any damage.
This product makes it easy to change your mirror's position or take it down completely with minimal fuss. You don’t have to worry about leaving holes in your wall.
You’ll need to work out the size of the mirror first to decide on the right size and number of strips to use. Also, not allowing enough time for the strips to stick to the wall before mounting the mirror is another reason why the mirror can fall off.
