This box-shaped shoulder bag from the KURO series uses reflective material on the triangular pieces, causing the entire bag to reflect light three-dimensionally in dark places. In bright places, the metallic texture becomes apparent. It's a convenient item for when you're out and about with minimal belongings. It has a zippered inner pocket for convenient storage of valuables such as wallets and keys. It's a single-layer design with no lining, using high-density fabric.
