This is a Porter "KLUNKERZ" messenger bag (L size) from Yoshida & Co. The main material is a fabric woven with high-density 500-denier Cordura nylon yarn, which is resistant to friction and tearing, and is likely quite durable. I don't remember when I bought it, but I haven't used it much, so I think it's in good condition. Color: Black系 (Black-based) Accessories: None
