The ring flask functionally comes with a well fitted cork and a capacity of 12 ounces. Aesthetically, it has a beautiful and even glaze while fitting the hand well. I could not be happier with the flask and highly recommend it.
I have only seen one of these before, which we discovered in an attic of a house that we were working on. It has been about 20 years ago, or more and I have since lost my written details. It had a name and date, written to the effect of, " John Smith's ring jug 1790". It did look so much like this, but had a very aged patina. We tried to research ring jugs but came up empty handed. This is the first I've seen since.
