Yes. I had no idea where they were used before reading about it in TGT.

All I was told when I bought the box was that they came right from the manufacturer (no location or anything else)... A woman in NOLA had several boxes at the time and I was lucky to wind up with one box. From what I remember; she sold all that she had to someone in TX, and remembered she had another box when she saw one of my newspaper ads...
