Best. Thermos. Ever.
The makers of this seemingly indestructible thermos boast that it will not leak, dent, or break, and that it keeps liquids hot for hours. The thermos is made from high-grade stainless steel and has vacuum insulation to ensure that what is inside stays inside. The effectiveness of the insulation can be increased even further by pre-warming or pre-cooling the thermos with hot/cold water.
