Suica Penguin I exchanged for it with points, but I have no use for it anymore... Quoting from the official page: This is a JRE POINT exclusive product! It's a card case with a cute chocolate color and milky white that makes you want to eat it. It's an excellent item that reads the IC card on the side you hold up, even with IC cards on both sides. Size (approx.): Width 6.5 x Depth 0.7 x Height 10.6 cm Material: ABS resin Specifications: Can hold up to two IC cards, one on each side. Reads the IC card on the side you hold up.
