A tiffin carrier is like a special container for food. Usually, it has three or four layers, and each layer can be stacked on top of the other. It helps to keep the food warm or cold, depending on what food you have inside. It has a handle on the top so that you can easily carry it around with you. It's like a lunchbox, but instead of putting your food all in one container, you can separate your food into different compartments. It's very popular in countries like India, where people take their lunch to work or school. They can use the tiffin carrier to carry different types of food like rice, vegetables, and curry. It's a great way to keep food fresh and separate different dishes without mixing them together.
