This is the take-home puzzle kit "The Lost Item Detective and the Song That Vanished Among 10,000 People" from SCRAP. I have played it. There are no writings or stains (stains on the evidence are part of the design). Some paper parts had their perforated lines cut as they were necessary for the game's progression, but these are essential for solving the puzzles and do not affect gameplay. There are traces of the seal and some minor tears from opening the paper envelopes containing the contents. There are no issues with the game's progression, but please refrain from purchasing if you are concerned about these details.
