Color:Stainless Steel  |  Size:500 ml What is a vacuum flask? It’s a thermos that has two layers from which the air has been evacuated in a nearly gas tight enclosure. This provides a better insulation performance than conventional insulation materials. Often the inner layer is glass, which is notorious for breaking if you ever drop your thermos! Our vacuum flask is stainless steel on both the outside layer and the inside layer! It’s NOT going to break! We designed a vacuum flask that’s going to last. It’s strong, corrosion-resistant stainless steel, fashioned in a streamlined shape that’s lightweight and fits in most car cup holders for convenient transporting. It will keep your hot beverages hot or cold beverages chilled for hours. It holds 500ml (16.9 oz.) of your favorite beverage, from hot coffee to a frosty smoothie in the morning, or a batch of your favorite cocktail for the tailgate party! It’s completely leak-proof when closed, and you can just open the spout and pour without removing the stopper. The stainless cap has the same sleek lines as the flask, and is also a drinking cup! This is a great gift idea for family and friends, and would be easy to have engraved for making personalized groomsmen gifts as well!
