Mexican shot glasses, raised blue siral design. All of the sets of shot glasses we offer are handcrafted in area around Guadalajara, Mexico by individual Mexican artists, using glass-blowing techniques perfected over generations. Please note that as each piece is individually handmade, slight variations in the shape and size of the glass are likely, making every item a distinct example of blown glass craftsmanship. Tiny bubbles within the surface exemplify this singular, rustic technique.
