May People Know- 20 oz. Viking Tumbler

These tumblers are an absolute necessity! :) I usually have one going with coffee and one with water all day long. They will keep your cold drinks icy for at least 12 hours, and hot drinks piping for 4-6 hours. 20 oz tumblers feature double wall insulation, copper lining and a press-in, twist-closure lid with a vacuum seal. Viking tumblers give you high quality, insulated drinkware. Care instructions: Hand wash only.
