Ichiban Kuji Pokémon Masters EX 7th Anniversary

Ichiban Kuji is a Japan-only lottery system sold at convenience stores (Seven-Eleven, Lawson, etc.), book stores, and hobby shops. Each ticket costs around ¥860. You draw a ticket and win a guaranteed prize - no duds. Popular anime kuji sell out within hours, especially for cute characters. For overseas fans: Since this is Japan-exclusive, the cleanest way to buy is via proxy services like Buyee, which buy from Yahoo Auctions / Mercari / Suruga-ya on your behalf and ship internationally.
