This is a bonus item from a vacation package. Used 3-4 times. There is a light stain on the bottom (last photo), and there are no other noticeable stains, but please refrain from purchasing if you are concerned as it has been stored at home for many years. When you open the zipper on the bottom, it becomes a sheet with thin cushioning material, but it is unused. Size: 31 x 37.5 x 7cm (approximate size) Shipping will be done using recycled materials. Eco-Mercari shipping is not available.
