I would be inclined to reply - "the dictionary definition of repairable is "in a state whereby the item can be made good by any process" and it is clear that there is no way to make these bats good. You will also wish to note that you omitted the main damage from the photos stated, which created what I believe to be a deliberately false perspective on the future useability of the bats. Your call, but I am confident that ebay will invoke their buyer protection in this instance"
