This is a small backpack for children. It's a muted blue color, though it might be hard to tell. (I've included images from the website for color reference, as the size may be different.) I don't think there are any noticeable stains. It hasn't been used many times, so the bottom is also clean. Currently, it's set for "Rakuraku Mercari Delivery," but it may be shipped via "Yuyu Mercari Delivery" depending on the packaging.
