The copper jigger may be the most underrated barware accessory on the market. This chic tool is specifically designed for precision when measuring cocktails and mixed drinks, but lends itself quite well to elevating your barware aesthetic in nothing but an elite fashion. Our hammered and smooth-finished copper jiggers both hold one and two ounces on each end of the vessel. And if you thought you could get away with a simple shot glass instead, think again.
