I also received this from an acquaintance. Both the keyboard and mouse show signs of use, but there are no noticeable scratches. There is no box or manual. The acquaintance who gave it to me is wealthy, so he apparently disposes of boxes and manuals immediately. This is not stolen property, so I've included a picture of the label. The acquaintance retired from gaming after his wife told him to "stop playing games." Mr. Taka is a computer enthusiast but not a gamer, so he doesn't understand the appeal of this product. I have already given my acquaintance a generous thank you, so please refrain from asking for a discount. Please only purchase if you understand the product based on the label. *It is in working condition and has been tested.*
