155 Briefcase

Vegetable tanning represents the oldest method of leather production, using natural tannins from tree bark in a process that takes weeks rather than the hours required by chrome tanning. The result is a material that ages rather than deteriorates, developing a patina that records years of use in deepening color and softening texture. Grams28 selects 2mm full-grain hides processed through this traditional method, ensuring the 155 Briefcase improves with each passing season.

At 40 by 30 by 7 centimeters, the proportions accommodate contemporary work tools within a silhouette that would appear at home in mid-century photography. A central padded sleeve suspends 15-inch laptops away from hard impacts, while accordion pockets on either side organize notebooks, tablets, and portable chargers without bulging the exterior profile. The document compartment closes with concealed magnets, eliminating visible clasps that would interrupt the leather's clean plane.

Hand-finished edges demonstrate the care invested in construction, with painted and burnished seams that resist fraying through years of handling. Raccagni zippers from Italy provide the smooth operation expected at this price point, their teeth engineered for the thousands of cycles a daily-use bag demands. Custom zinc hardware throughout uses a muted finish that complements rather than contrasts with the leather tone.

The shoulder strap incorporates automotive-grade webbing on its underside, distributing weight comfortably during commutes while maintaining the leather exterior appropriate for professional settings. Metal feet protect the base from damp floors and dirty platforms, a small detail that prevents the staining that ruins lesser bags.

Microfiber lining inside resists the ink transfers and coffee spills inevitable in working life, allowing cleanup without permanent marking. The 155 Briefcase treats the tools of knowledge work with appropriate seriousness, housing them in materials and construction that match their importance.
