Made in the 70's. A direct competitor to the Sip and Strip line. These sets put out by Fishlove and Co. feature the clothes that disappear when damp. A rebirth of an old technology in a cheesier form. Sold as a set of 4 glasses. The first two glasses in this set are in better shape than the last two. But I have not seen many of this set available. I put in the black ovals on the reveal.
