6-Hole Tequila Cocktail Shot Holder, Shot Glass not included

A shot glass is a glass originally designed to hold or measure spirits , which is either imbibed straight from the glass ("a shot") or poured into a cocktail ("a drink"). An beverage served in a shot glass and typically consumed quickly, in one gulp, may also be known as a "shooter".
Shot glasses decorated with a wide variety of toasts, advertisements, humorous pictures, or other decorations and words are popular souvenirs and collectibles, especially as merchandise of a brewery.
In early America when we still hunted our meals regularly, a small glass would be left on dinner tables at each table setting in which guests could place the lead shot or buckshot that may still be in their meals, eventually leading to the coining of the term "shot glass."
