Purchased at a gadget store. Length: 52cm, Width (when the gusset is closed): 67cm, Gusset: 8cm So, it can fit a slightly large pillow. Please understand that there may be some slight variations. It comes with individual bags, so you can put in two items, fold them, secure them with Velcro, and hang them on a clothesline. (Photo 5) I threw away the outer bag, but it said it was for protection against pollen and that the black color absorbs sunlight easily. I used it for pillows and also for laundry, and I would put it on the roof. I used it about 7 or 8 times, but I haven't used it for about 2 years and I don't think I will use it anymore, so I will wipe it with a disinfectant sheet before listing it. There is one white scuff mark. (Photo 6) Please understand that this is a used item. #gadgets
