This is a briefcase from Postalco, which is now discontinued. I believe the original price was around 140,000 yen. It's made of crossgrain leather. The following is from the official description: As the name "crossgrain" suggests, a small diamond-shaped grid pattern is pressed onto high-quality cowhide (steerhide). This pattern not only enhances the appearance but also makes minor scratches from use less noticeable. Steerhide is a tough leather used for belts, etc., and is thick and highly durable. Height: 30cm, Width: 35cm, Depth: 7cm The black leather and hardware, which appears to be brass, give it a luxurious feel, making it perfect for a work bag. It's been well-used and has a worn-in look, but it's still in good condition and can be used for a long time. Color: Black Material: Genuine leather Features: 2-way Accessories: Shoulder strap
