This is a MUJI sacoche bag. I purchased it three years ago and used only the strap a few times. The main pouch part has been stored unused. It was stored with silica gel, but there are orange-yellowish stains on both sides of the inside, aligned with the top of the middle divider. I've included photos 6 and 7, but they didn't capture it well. You can find them if you spread it out in a bright place. There were no noticeable discolorations on the front. Please understand that this has been stored for a long time before purchasing.
