The manhole card from Maebashi City, Gunma Prefecture has a lot number of 012. It will be sent via regular mail, in a sleeve. It was put in a sleeve when I received it, but since it has been handled once, please refrain from purchasing if you are looking for a perfect item. Please also check my profile. I will try my best to prevent it from bending, but I cannot be held responsible for any bending that may occur during shipping. Please also check the photos carefully. Type: Single card, 1 card
