Magnetic Hook

Useful hook that you can either stick with double sided tesa tape like this:

TESA

to a flat surface.

Or you can just use small cylinder magnets of 5mm diameter and 3mm thickness like these:

MAGNETS

The hook is 10mm of width and it withstands 13mm. With the magnets I am using it is strong enough to hold a pair of small scissors, a key or a towel.
