I purchased this item from another auction site in 2021. The previous seller had only used it for mountain climbing about twice. There were some missing parts, but I was satisfied and purchased it for 8,000 yen. There was no box or instruction manual, so I searched the Cotton Carrier official website for how to secure the camera (^^; The missing parts are the hand strap and the drop prevention strap. When I attached the camera to my backpack, I always had the camera neck strap around my neck, so I didn't have any problems without these straps. The camera can be easily released and locked with one hand. It's difficult to detach when locked, but I think it's best to keep the camera strap around your neck just in case. According to the Bic Camera online shop, which I referenced in the photos, it seems to be currently selling for 10,980 yen. (I believe it's the same or a similar current product. I apologize for not being clear.) There are also missing parts, and I have used it three times (one season) for long-distance trekking, so I would like to sell it. There are no scratches that would interfere with use, and the construction itself is very sturdy, so I think it can be used without any problems. However, please understand that it is a used item. If you are interested, please consider it.
