This set includes 30 covered plastic containers, which are in sufficient quantity to meet both daily usage and replacement needs. They are suitable for holding various foods such as pies, egg tarts, doughnuts, salads, etc. The containers are made of transparent PET plastic, which helps maintain the freshness of the food. The transparent design provides clear visibility, allowing for an intuitive display of the food's condition and the appearance of baked goods. At the same time, it can prevent air, moisture, and potential harmful substances from entering, locking in the food's flavor, texture and color. The containers can be stacked for storage, making them highly portable. They can be used for food storage, picnic packing, and are also suitable for use in catering establishments such as bakeries, cafes, restaurants, and takeout shops, preventing food damage during transportation.
