The mini backpack, when laid flat, is approximately 7" tall and 8" wide at its bottom. It has been in storage laid flat for quite a few years, and does not stand up when it is opened. It is a clear vinyl like material that is on the stiffer side. There are yellow spots and streaks on the inside of the top flap, and reddening around the blue stitching. The backpack has scratches and scuffs throughout. The straps are adjustable, they are creased. The towels inside are for showing what it looks like full, they are not included.
