12 oz. Wine Tumbler

The Wine Tumblers are more than just a stainless steel wine glass, but rather a multi-function cup for any beverage.

They can keep your cold beverages cold for six to nine hours and your hot drinks steaming for up to three hours.

Features an easy-to-sip opening with a water-tight slider lid, a stainless steel straw, and a cleaning brush for the straw.
