Beautiful Daisy and Button Crystal Corn Holders UNIQUE!

These look like holders for corn on the cob to me, but they may have served another purpose. They are clear in the daisy and button pattern. They are slightly curved on the side and I believe they were made by Indiana Glass. They measure 7 inches long and about 4 inches wide. They are in perfect condition with no chips or cracks. I was unable to find anything like them on the web. So, if you know they are something different, go ahead and tell me, I love to learn new things about my stuff!
