I purchased this at Tokyu Hands in Shinjuku. My husband loved it and used it for four years. He says the zipper opens and closes very smoothly, and it seems to be easy to use. It has a used feel overall, and as shown in the photos, there are some areas where the material is starting to peel. If you don't mind, please consider it♪ The included shoulder strap is new and unused, and I will include it.
