I love whimsical things and had to get these when I saw them. They are made of thick, sturdy, cast iron. I was originally going to place them outside on my lanai to hang small pots from them but thought that the Florida humidity may cause them to rust. I just had my husband put them up. The only thing he said was that the screws should be a little bit longer for sheetrock. He ended up using his own screws. I really love them!
