I purchased this from Amazon about six months ago. I only tried putting a camera in it, and it has been stored unused since then. I haven't had many opportunities to use it, as I rarely take enough equipment with me to warrant bringing a backpack. I also purchased the optional premium belt, thinking it might be useful, so I'll include that as well. Purchase price: ・WANDRD Stratus Photo 18 ¥35,000 ・WANDRD Premium Belt Black ¥9,020 I really like it, but it's a waste to leave it unused, so I'm putting it up for sale. Thank you very much.
