Is there such thing as an actual insulated lunch box? I want something like a thermos but it's a lunch box. Would probably have to me made of metal and hollow inside the walls. Even the offerings from yeti suck and don't actually hold in temperature.

Yeah I know coolers exist but I need something compact
