The piece is made of PU leather, a synthetic leather chosen for its soft, supple handfeel and smooth surface. This exterior gives the piece a premium look while remaining practical for everyday use, and its soft structure suits the relaxed, casual commuter style of the design. The clean solid-color finish and horizontal square shape fit a Korean-Japanese aesthetic that works easily with daily outfits. Inside, the lining is polyester, a durable and easy-to-maintain material that helps protect the contents. The strap is also faux leather in a matching synthetic leather, and it is adjustable so the length can be set to different heights. The hardware is zinc alloy, and the piece closes with a magnetic snap.
