Pokemon Center 2018 Rainbow Rocket Campaign Golisopod, Hydreigon & Friends pass case. This limited edition pass case was only sold at the Pokemon Centers in Japan for a very limited time and in very limited quantity, in January, 2018, during the Rainbow Rocket campaign. In Japan, most people have a magnetic pass (like a credit card) that they use instead of buying tickets. They swipe it over the gate entrance and it takes the money out of your card balance. This case has a plastic window to put your ID or magnetic pass card in. It also has a pocket inside to put coins or other small items in. Made of a leather type material (immitation leather).
