YEE SI reinterprets and designs the modernist bag Liquor with its flexible folding language and elegant and concise appearance. In addition to liquor bottles and portable water glasses, the Liquor Vertical bag balances brand aesthetics with more energy. Two parallel triangles together form a cube, which is a fluke to illustrate the beauty of geometry. Folded lines are embossed to emphasize the harmony of understated. The portable belt extending from both sides of the bag body can be tactically installed through the metal socket to meet more practical needs.
