【Distribution has already ended】 This is a complete set of the "Secret Travel Campaign," a collaboration between JR Central's "Recommended Trip" and "Himitsu no Ai Pri x JR Central." This campaign offered special Ai Pri cards (3 types) as a boarding privilege on the Tokaido Shinkansen. These cards could be exchanged at Prism Stone stores in Tokyo, Nagoya, and Osaka (Namba), with each store offering a different design. ※ These are special Ai Pri cards that can be used in the amusement game.
