The piece is crafted from washed kraft paper, a low-carbon, eco-friendly material made from natural fiber pulp. This material is waterproof, tear-resistant, and free of harmful substances, while also being recyclable, biodegradable, and reusable. The body is sturdy, durable, thick, and structured, resisting damage while offering a smooth hand feel. Its unique texture and solid black color align with a casual, street-style aesthetic, making it suitable for everyday leisure scenarios and year-round use. The soft handles are made from smooth, comfortable nylon to enhance the carrying experience, and the large capacity supports multiple daily uses. The front features a screen-printed logo and material-character text, adding a graphic, print-focused detail that fits the piece's relaxed, urban look.
