Especially created for the connoisseur who prefers accuracy, this is the tarnish proof, aluminum alloy, 4 to 1 measure. It is 11" long with a measure on either end. The larger measure is 4 times larger than the smaller - yes, 4 - 1. I have one of these & find my Plymouth Gin martini is perfect when I use the large end twice, small measure once > 8 to 1 martini. Comes with original box, instructions/insert and cleaning directions. This is a great one.
