This is a set of two dam cards from the Aigawa Dam and the Minoh River Dam in Osaka Prefecture. Both cards are the latest versions, recently updated! Please note that the back of the Minoh River Dam card has a slight scratch, noticeable when held up to the light, as it was when I received it. After obtaining them, I immediately placed them in sleeves and have stored them carefully. I will reinforce them and take measures against water damage, and ship them carefully via standard mail or mini-letter. Thank you.
