The main problems of espresso boxes (cooler bags) are their low durability, small size, no temperature control, and easy damage. The solution includes the use of medium-sized bags that are durable, equipped with a temperature system, small fan, battery, and suitable for hot and cold materials. These features help maintain the temperature of the materials, prevent damage, make it easier for users to carry and store, and save space. This innovation provides users with the convenience of storing more materials without compromising the quality of the temperature.
