This is the Atelier Blue Bottle Hikers Sacoche R. I purchased it at an event. I took it out of the bag intending to use it, but it's still new and unused. I threw the bag away. There are two sizes for the shoulder strap, and this one is S-M. It cost a little over 18,000 yen. The price includes shipping and handling fees.
