This is a set of three Dam Cards from the Aigawa Dam in Osaka Prefecture: the Expo Commemoration Dam Card, the regular card, and the 1st Anniversary card. The Expo Commemoration card distribution ended on October 13th. The regular card is a new card that has just recently begun distribution. After receiving them, I immediately put them in sleeves and carefully stored them. I will reinforce them and take measures against water damage, and ship them carefully via standard mail or mini-letter. Thank you.
