In the product description - for whatever reason - not identified any METALLl the pots were made, so I do not know whether they will rust.
BECAUSE:
Unfortunately, they also have a hole in the ground. Consequently, I have a bored, so that the flowers do not have to make the free float in the rain and go sooner or later!
The processing seems to be tidy. But that will have to if they have once hung a couple of weeks outdoors.
Should I still notice something, I'll write an edit.
PS:
A request to the seller: Please enter a detailed description of the metal from which the pots are made.
Sheet metal, zinc, aluminum - or whatever ?????
Finally, one would like to throw out any money for stainless pots at the window!
Edit from 13.05.2015:
After a few days of use outdoors RUST metal !!!
For those who buy these pots:
No holes drilling !!!
Like the flowers react when - for lack of water flow - after a downpour for days must stand in water, can probably imagine everyone:
YOU GO ON !!!
I would buy these pots again!
