Advantages of choosing a cooler during the winter include:

       1. Preserve temperature-sensitive foods: Some foods are prone to spoilage at higher temperatures. Using a hand plastic cold box can keep them within a suitable temperature range to  ensure the freshness and quality of the food.

       2.Storing outdoor supplies: For example, during winter outdoor sports or camping, the ice cooler can be used to store drinks, food and other necessities to ensure that they are kept at a suitable temperature, making outdoor activities more comfortable and convenient.

      3.Frozen food and ice cubes: In winter, the ice chest cooler can be used to frozen food.

      4.Portable: Coolers are generally portable and suitable for outdoor activities, picnics and travel, keeping food fresh and warm even in the cold winter.

Therefore, there is still a need for coolers in winter, which provide us with many conveniences and functions of preserving food.
