I purchased this last year when I took the Disaster Prevention Specialist exam. There are no markings, and it's in very clean condition. As you can see in the third photo, the corner is slightly warped, but it's not folded. I'd like to pass it on to someone who needs it. Regarding shipping, it may take a little time. If you're in a hurry, please consult in the comments section. I may change from Rakuraku Mercari shipping to Yuuyu Mercari shipping.
