5-Minute Unexpected Endings 2: Blue Mystery 5-Minute Unexpected Endings 4: Black Humor - Publisher: Gakken - Series: 5-Minute Unexpected Endings I read these once and then stored them. The Blue Mystery has a tear and a fold on the cover and the corner of the book. There are no noticeable stains, but there are some minor scratches, so please refrain from purchasing if you are sensitive to such imperfections. Thank you for looking.
