I read about these on another message board I go to, and I had no idea what they were talking about. They were talking about how great they were, etc., etc. And I had no clue. And then somebody gave me a link or explained it, and I think I may have sat at the computer with my jaw dropped open. I saw them in the store and couldn't believe my eyes! I told my mother about it last time I was visiting and she refused to believe that they existed and that people used them.Â
