Pair of Stanton’s Ltd Botanical Breweries jars from Bolton in the UK. Used for various drinks, Beers and lemonades, such as Dandelion and Burdock. The jars were so useful that people kept them to use as hot water bottles and as door stops filled with sand. It was such a problem that the company put a warning on the jars.
"Any person refilling or detaining this jar will be prosecuted”!!!
