Hello everybody. Once upon a time in Soviet times, I saw a magnetic soap dish at a friend's house. But on sale such never met. The thing is actually very convenient. I made myself one. Unfortunately I can’t take a picture. I'll tell you in pictures. In household goods, towel holders are sold. They are different, sold assembled and separately in parts. They look something like this:
We take one part, where the tube should be inserted, glue the magnet
Then we attach to the wall in any way possible.
Next, take a steel (non-rusting) watch cover
And squeeze it into the soap.
You can certainly use a beer cap, but it will rust very quickly. Soap dish is convenient in that the soap does not get wet, does not turn sour and does not stain anything. I have been using such a soap box for 10 years now.
