Review on Norpro Muffin Rings Set 4 by Tanya Hughes

I hand washed these but they sat in the sink for a few hours before I got them. They were slightly damp in the sink and rusted before I even washed them. I can't use it because of rust. They didn't sit in still water, and it didn't even occur to me that sitting with other dishes would rust them. I'm frustrated that I'll never use them, so I don't really get to know how they work.
