Nikkai 7-Litre Cooler/Heater Box

As this costs the same as some much larger boxes, you’d have to use it a lot to justify the outlay. It can take 12 330ml and six 500ml cans, cooling them rapidly to 21 deg C below ambient temperature. There’s a shoulder strap, warming option and snug can-holders in the lid, but annoyingly no lead storage.
