These unique casseroles are dual walled, along with a stainless steel interior surface that helps keep food hot, healthy and fresh for long hours. The leak-proof lid does not allow the odour of food to escape. This helps retain the flavour of the food stored in the casseroles. The stylish and functional lid fits properly, keeps food airtight, and can be easily opened by twisting it sideways. Buy this today on Flipkart.
