The black marks will also be black! I used this in high school, but I'm giving it away because I no longer have a use for it!! It's made of sturdy material! The inside is very clean, but there are some scratches on the sides and bottom. Please check the images. I feel like there are no problems using it! And there's a part on the bottom that I fixed with a little super glue around the beginning of my third year. Please check the images. If you look closely, you can see some scratches, but I think they're not noticeable overall! (This is just my personal opinion) The bottom is slightly peeled, and as expected, there are some areas that are scuffed from being placed on the floor, so I would appreciate it if those who are concerned would refrain from purchasing. I am accepting price negotiations, so please feel free to ask! I can't offer a significant discount!! I look forward to your purchase!!
