Material and Craftsmanship Main fabric: Made of high-density nylon, it has waterproof and scratch-resistant properties. It is easy to clean and durable for daily commuting. Handle/Bag cover: Complemented by tanned brown cowhide, with natural and fine texture, creating a contrast in texture with the nylon, enhancing the overall sophistication. Function Design Capacity Optimization: The package is square and three-dimensional, with a main storage layer, a front zipper pocket, and built-in multi-functional compartments, which can accommodate a 13-inch laptop, folders, and personal items. Handle Comfort: The wide leather handle (measured at approximately 3cm in width) fits the hand curve and does not cause hand irritation even after prolonged carrying. 3. Visual Aesthetics Color Scheme: The dark blue body conveys a stable and business-like feel, while the brown leather handle and gold accessories inject luxury elements, suitable for various scenarios such as the workplace, leisure, and socializing. Minimalist Design: There are no redundant decorative lines. Only material contrast and metal fasteners are used to highlight the design, conforming to the modern minimalist aesthetic trend.
