Fino 13 oz Stackable Tumbler Cups - Set of 6 Insulated Stainless Steel Drinking Glasses for Hot & Cold Beverages - Perfect for Coffee, Tea, Juice, Smoothies at Home, Office or Outdoor Picnics

Based on their original award-winning stackable series, the Fino model is much thinner and more refined. Despite the super thin glass used to make them they are surprisingly durable thanks to Toyo-Sasaki's patented ion toughening technology.
