Using this vintage Hungarian enamel lunchbox tower is a breeze. You can stack your food in the three bowls and cover them with the lid. The handle makes it easy to carry around. When it comes to cleaning, use a mild dish soap and a soft sponge. Avoid using abrasive cleaners as they may scratch the enamel. Store it in a dry place to prevent rusting. If you're using it for lunch, make sure to let hot food cool down a bit before putting it in to avoid damage to the enamel.
