I believe I bought this last year. I liked the fluffy texture and color, so I bought it, but I always have a lot of luggage and haven't had a chance to use it, so I'm selling it. I've only used it once. There's a removable square inner base inside. The inner base is soft. When you fasten the buttons on the bottom, it becomes a small bag. When you remove the inner base and flatten it, it's about 30 cm tall and about 40 cm wide.
