Awhile back I saw a lip guard to fit over the brim of a metal drinking cup. This was NOT the PLASTIC RING that many folks use for the Fosters and Heinie pots but a plastic device approximately an inch a ½ to two inches long. It was just wide enough to protect lips when drinking a hot beverage from a metal cup. A search in Google and here at BPL has not turned up the little device.
Does anyone know from this description what I am looking for and where to find it? Thanks for your help,
John
