Here's a set of 6 insulator shaped schnapps cups made by the Rosenthal Insulator Group and stamped in orange ink with RIG on one side and Warning and High Voltage (in German). Only 3 shown in photo but you get a group of 6. I believe these were originally sold as a set with the RIG schnapps insulator bushing shaped decanter. Very few actual go-withs can be confirmed to have been made by an insulator manufacturer so this is an unusual example.

First email gets this rare set of 6 insulator schnapps cups in factory mint condition for only $350 plus shipping. Or buy only one for $55 postpaid. Thanks!
