I purchased this about two years ago and used it a few times, but I wasn't sure what to store in it, so I haven't used it and have been storing it. I believe the size is M, flat size. Everything in the photos is included. There is one long divider and six short dividers. I have a cat, so there may be some hair on it. I will remove it with adhesive tape, but if you are concerned about allergies, please refrain from purchasing. I am also selling other camping gear, so if you purchase them together, I will offer a discount. Please take a look at my other items.
