From the bottom of the tumbler, sleek colored lines rise, highlighting the thickness and embellishing the contour, up to the shiny rim. "Tirache" is the Venetian name for suspenders: an elegant accessory, a sophisticated touch of style. Available in both two-color and one-color versions, the Tirache tumblers are made of mass-colored, mouth-blown and handcrafted glass. Dishwasher safe at 60° C.
