This is the limited edition WALLHACK SP-004 FAITH YUME. It was a limited release of 4000 pieces and is no longer available on the official website. This is No. 602. I used it for about a year, but I alternated with other mousepads, so the actual usage time was less than a year. There are no noticeable scratches or stains. Please refrain from purchasing if you are concerned about minor scratches or stains. Sticker included.
