My father likes to have a clock in our bathroom. Currently, it looks like this:
As you can see the clock is already damaged because we need to move it all the time when we want to open the window. I would like to mount it on the wall, but we have tiles there and cannot drill a hole there.
The clock has the usual "hole" to mount it on the wall with a nail:
I would like to have something like TESA powerstrips which holds very good, but with a knob on it so that we can easily put the clock on the wall and remove it if the battery runs out. How is something like that called?
