Adopting the classic retro diamond grid stitching technique, the pattern arrangement is neat and full, with a full sense of three-dimensional unevenness. Selected wear-resistant fabrics paired with delicate leather edging ensure even and dense wiring throughout the vehicle, with smooth and delicate edges that are not easily cracked or worn. The flip cover is tightly closed, paired with a metal lock buckle, opening and closing smoothly and with outstanding texture. The body shape of the bag is firm and three-dimensional, not easy to collapse or deform, with reasonable internal zoning and convenient storage. Can be carried by hand, shoulder or crossbody, with a strong retro charm, classic and durable design, and easy to enhance the overall style with daily matching.
