Dakine Backpack, Neon green interior, padded laptop pocket

For work, school, or travel. Five pockets on the front, including a back, small pocket for wallet, kets, etc, a large padded pocket for a laptop, a medium pocket with an area for pens, a small front zippered pocket, and an even smaller slip pocket. There are 2 more pockets on the sides, one which can hold a water bottle. Used Condition. Signs of wear exist around the bottom (see photos) and there are some ink stains inside the middle pocket, despite me cleaning it several times. I'm sure it's just user-error. I guess I don't know how to properly remove ink from fabric 🤷‍♀️ Zippers and structure are all in great shape! feel free to give me a fair offer!
