This solid aluminum cube was designed by Josh Owen. To quote the designer, “the design of the aluminum cube jigger evolved from an experiment to compress the six most common liquid measures used to mix alcoholic drinks, into the smallest possible dispenser.
The form was inspired by traditional box-shaped, Japanese sake cups, from which sake is sipped from the corners. The six measurements are .5 oz, .75 oz, 1 oz, 1.5 oz, 2 oz, and 2 1/4 oz. The cube measures 3 inches per side and weighs a full pound. There is a recipe book included which has directions for 14 favorite cocktails.
I was really confused, and this answered all my qeuitsons.
