Steph, it's been a long time since any have been offered on ebay, but my recollection is that they are extremely colorful striped opaques. Not sure if they came as striped transparents. I never heard of any that were not mint, which is a little unusual. I have seen what were called "circus marbles" at a couple shows and these may have also been the same thing as the "exotics". They too are very colorful and bright. As far as I know, they only came in small sizes. It would be nice if someone would post a photo of one. Surely someone who reads this board must know someone who bought one once upon a time....Actually, Alan Basinet must own some exotics if anyone does.
