This is a dinosaur bag by MIHARA YASUHIRO. It's made of nylon and has an adjustable strap. It's a good size for a folding wallet and a few small items. The retail price was around 70,000 yen. I purchased it from an authorized retailer. I've used it a few times, but I think it's in pretty good condition. I can also provide the receipt from the purchase if needed. Thank you.
