While there are some minor scuffs and scratches from use, there is no major soiling, and it is still in good condition. It is very smooth. The top beads can be cleared with a single touch. *There are traces of stickers that were received upon promotion, on the top. They are not immediately noticeable, but can be seen upon close inspection. *The case is also relatively clean, but please consider it as an extra.
