These hand-hammered cups are made by an international cooperative of master copper artisans, with workshops in Austin and Santa Clara del Cobre, Mexico. Made from 100% recycled copper, each piece is made to last a lifetime. The Tequilero cup is based on the traditional Mexican 'Caballito,' or 'little horse,' a tall and thin glass ideal for sipping tequila or other spirits. Try it for mezcal, aquavit, or sake. Copper is an inherently clean material with antibacterial properties; it never changes the flavor of beverages. The copper is unlacquered and will age with time and use to a beautiful rich patina. Hand wash only. 2.5 oz.
