I bought this new a while ago, but I haven't used it, so I've been storing it at home. It seems this product is no longer sold. It's popular and has become a rare bag. Due to aging, the part indicated by my thumb in the third photo has become sticky. However, I read that soaking it in baking soda and washing it should remove the stickiness! (I haven't actually tried it, so I'm not sure...) Please consider purchasing this item with the above in mind.
