Thermo-Pot
If the old school Thermos you used to tote to school saw a modern upgrade, it might look something like the Black + Blum Thermo-Pot. Holding up to 17 ounces, this vacuum food flask features a biodegradable cork, polypropylene and silicon top, stainless steel body, and an ergonomic stainless steel spoon that magnetizes onto the side when it's not in use. It promises to keep the contents hot for up to 6 hours and the vacuum even comes with a 10 year guarantee.
