Handbags are designed to keep products fresh. However, the freshness period of the products may vary depending on the air circulation inside the bag, storage conditions and the type of product. The holes in the carry-on bags allow air to circulate inside the bag, which helps the products stay fresh for longer. For example, vegetables and fruits should generally be stored in cold and moist environments. However, some vegetables and fruits, especially tomatoes, should not be stored in cold environments because the cold can spoil the taste and texture of tomatoes. Therefore, when using carry-on bags it is important to consider the conditions in which the products will be stored and the type of product.
