I purchased this in May of this year, but I'm selling it because I don't seem to have a need for it. The following is the product description from when I purchased it↓ It's a Workman lightweight 3-layer pocket mother's backpack in black. I bought it at the end of March and used it a few times. There are no noticeable stains, but there's a small snag on the right side of the front double zipper (photos 5 and 6). ※ Personally, it's hardly noticeable. It has a lot of pockets, so it's recommended for those who want to sort and carry a lot of things. There are pockets on both sides inside to hold bottles, so it was convenient to put a water bottle on one side and a folding umbrella on the other, so they wouldn't get in the way. A4 size fits easily.
