This is an excellent, like new Thermos Canister that is great for transporting hot or cold food for meals on the go. It is a newer design with a Stainless Steel Insulator, Removable Plastic Reheatable Container and a lid that screws on to prevent spillage ... yup even including soup! There is a silicone seal inside the lid and when screwed on properly does not leak. The plastic food holder insert is dishwasher safe.
