The Built Stainless Steel Soup Mug is the ideal choice for eating soup on the go. With a vacuum insulated body that keeps the temperature of the contents consistent, you can enjoy warm food for up to six hours. The double-layer wall allows for a superior insulated container you can depend on to keep your food hotter, colder, fresher, longer. Most importantly, a leak-proof system that keeps all liquids from spilling inside your bag. The spoon nest on the lid and magically lifts as you push on its back.
