Collapsible Rolling Insulated Cooler Bag with Wheels

In the hot summer, when you go out, you really want to have a cold drink in your hand. In the cold winter, when you work outdoors, you really want to have a hot meal. Our company recently launched a pushable and towable incubator trailer. The trailer is small and exquisite when folded, and can hold dozens of bottles of drinks or lunch boxes when unfolded, allowing you to feel the taste of home in the wild.
