Although it is new and unopened, the bag has some damage. These are sleeves limited to participants of the Masters event. Since they are unopened, I don't know how many sleeves are in a pack, but according to my research, it seems to be 55. If this is incorrect, I apologize. I have multiple sets available, so if you would like to purchase two sets, please comment. I will offer a discount. #nobara_rare_sleeves
