This is a complete set of 12 types of "Snack CD Nostalgic Heroes & Heroines Hit Song Collection Vol. 1," including a secret track. These are 8cm mini CDs. They were probably unopened, but since they belonged to my father, I opened them before listing to check the discs. All of them were in perfect condition. #rina_showaretro #rina_8cmCD I also have other 8cm CDs for sale. ・Kamen Rider "Let's Go!!
