I have a bunch of double wall decorative containers I purchased from Lowes
on closeout 6 years ago, same type of construction, solid bottom as well,
I see no signs of deterioration yet, and they get abused a bit when moved around.
Drilled some holes for my use.
The whiskey barrel version they sell is single wall,
have no experience with that style pot,
does not look as durable as double walled ones.
