This KURO series vertical shoulder bag is characterized by its fine, supple pieces. This series uses reflective material for the triangular pieces. When light hits the bag in the dark, its entire three-dimensional surface reflects the light. The metallic look of the material is apparent in bright places. The outside pocket has a hook for storing valuables safely. The convenient design allows the bag to hold a plastic bottle or water bottle vertically, as well as items such as your smartphone and wallet.
