Duel Masters Cards Selling over 300 cards in a bundle These cards were played with by my child when they were in elementary school, so the condition is not very good. Therefore, please refrain from making claims or giving negative evaluations regarding the product condition. Some rare cards may be included, but I do not have any knowledge of Duel Masters cards, so I will sell them as a bundle. I will take waterproof measures and ship via Yu-Packet Post.
