This is a business bag from M.R.S CLUB. I purchased it about 10 years ago, but only used it a few times and then stored it. It has many pockets and spaces to protect items like a laptop. It also has a function to be used as a backpack on the back. The size is approximately 45cm x 33cm x 10cm. The shoulder strap is missing. I will ship it via Takkyubin (courier service).
