Free samples are available. The shopping bag is made of high-quality Oxford cloth material, which is light in weight and durable. This bag adopts a foldable design, and when the small bag is unfolded, it is a shopping bag with a large capacity (45*32*12cm). The large shopping bag is only the size of a handkerchief (9.5*21*2cm) after being folded, which is convenient to carry and does not take up space. There is also a metal snap button on the side, allowing you to store it easily without unravelling.
