Strong Magnet for jewelry boxes, Crafts & more with hole 12mm x 3mm

The primary reason to use magnet cups is to increase the attractive power of a magnet. 

 Once the cup is screwed in place and the magnet set, there is little chance of it ever popping out, whether accidentally or intentionally. However, if you think that you will ever need to remove the magnet and cup, you can file or cut a slot down the side wall of the cup.

Magnets are a great way to create a firm and stong closure with low visability.
