This is a brand new, unopened item. I found it at a store and bought it. I don't know much about Pokemon cards, but I heard that if it weighs over 112g, there's a valuable card inside, so I weighed it. I thought there might be some error, so I used two different scales and weighed it several times. I think it's 110g. I heard that there's a chance of a valuable card even at 110g. For those interested in Pokemon cards, how about it? Type... Pack/Box Type... Multiple cards
