There are inserts as well, including autographs. The ones you see here were clearance-priced at only $5 each, the cheapest I've found yet in Japan. Hopefully some will be left this weekend after I get paid!
There are plenty of packs and boxes too, as well as a small collection of idol cards. There are boxes and packs, as well as a few singles, for US card releases (MLB, mostly) and soccer issues. And plenty of CCG cards, mainly of the MTG variety.
Prices for most cards are standard - singles are 60 yen each and up, with inserts usually starting around 300 yen.
Mint Opa! Orawa is open 12:00-20:00 weekdays and 11:00-19:00 weekends and holidays.
