I bought the butter bell but could not keep my butter up in it. I turned it over and just sit it on the counter. It works fine and looks like it is sitting on a little stand. That might not be appropriate for an rv traveling down the road. "smile" I find the only time I get mold in mine is I use a butter knife to spread the butter on bread and accidentally get some bread in it. My mother kept her butter on the cabinet in a plastic container with a lid on it. It was always fine. If we get our RV up and running, I will probably use plastic so I don't have to worry about breakage.
