I like Kangning's Kangning pot to heat directly on the gas, and the lock box of the lock has strong sealing performance! Cleaning the corning pot is easier to take care of, but cleaning the sealing ring of the lock cover is a bit annoying, depending on which aspect you focus on!

Lunch boxes on the market can be roughly divided into three categories: microwave heating, heat preservation and self-plugging electric heating. No matter what material it is, you need to buy it according to your own needs.
