Duo Ebony 16oz Stainless Steel Double Wall Vacuum Avalon Tumbler With Lid (Water Bottle)

The tumbler has double-wall vacuum insulation, which keeps cold drinks cold and hot drinks hot for hours. It also prevents condensation from forming on the outside of the cup, eliminating messy water rings, and prevents warm beverages from burning your fingers. The flip lid is threaded to stay securely in place, and it protects drinks from splashes and debris when taking them outside and on the go. The Zak Designs tumbler has a capacity of 16 ounces and fits in most car cup holders for travel. Made from durable stainless steel, it should be hand washed to preserve the vacuum seal; all materials are completely BPA free and should not be microwaved.
