Keeping your food warm when you are on the go is important. Nobody likes to eat cold food anyway. The Black+Blum Thermo Pot will keep your food or drink hot/cold for up to 5 hours. It has a biodegradable cork, polypropylene and silicon top. This holds up to 17 ounces of fluid. The stainless steel spoon is a plus. A pretty nice pick up for people who take their own food to work.
