These containers are designed to keep food warm for an extended period of time and often come in sets of different sizes. They typically have a double-wall insulation system with a stainless steel interior and an outer shell made of a durable material, such as plastic or melamine.
The containers are used for serving a variety of hot foods like chapatis, rice, stews, and curries at the table, helping to preserve the food's temperature, flavor, and aroma. The ones in the image feature a decorative marble pattern with gold-finish handles and accents.
