When I planned the design for this magnetic cement key holder, I got an unexpected but pleasant bonus. I realized I didn’t need to add any mounting hardware to it because this cement key holder holds itself firmly to just a screw in the wall.
This was demonstrated when I had the key holder it in my hand, and as I went to turn on a light with the same hand, I could feel the key holder pulling itself to the screw in the light switch plate. It snapped itself right to it! If I had pre-planned that, it would have been genius, but it was just luck. :0\But seriously, how much easier can it get? It’s a no fuss mounting system.
The only tricky part is dealing with such a strong magnet when making this. *You really need to take precautions when handling a rare earth magnet. Make sure to keep it wrapped with bubble wrap, or put inside a thick plastic container and don’t get close to anything metal. These things can bite, so just be careful please.
