This is a puzzle called "To the End of the Arrow" from SCRAP (Scrap). It's a subscription-based mystery (commonly known as "Subsc-Mystery"), a type of puzzle that is delivered to your home every month. It's like a take-out mystery, available only through online shopping. The puzzle is contained in an envelope close to A5 size. The envelope has been opened once because I solved it. I made a copy and solved it, so there are no writings or folds. You can enjoy the puzzle as if it were new. I think it's clean, but it's a used item, so there may be minor scratches or signs of use. Please understand this before purchasing.
