Thank you for viewing. This is a dam card and commemorative stamp from the Shitara Dam in Aichi Prefecture. It seems they are distributing these for a limited time because the dam is currently under construction. I believe it is a very rare item. I will carefully package it to prevent bending and water damage before shipping. I have two sets available. If you purchase both sets, I will discount them by 100 yen. Please comment beforehand. Thank you.
