So about three weeks ago I sold my beat 2000 Concord 11s on ebay, and just now the buyer is opening a claim against me saying that they are not authentic. He is saying that the material of the box is incorrect, and that the inside tag has a production date of 6-15-30. The tag does have that production date, but everything else matches up and it might just be an error since those releases were prone to errors such as the batch of Space Jams that said "Air Jordna" on the box. Besides that, I am 99% sure that these are legit and I've had other people agree that they were legit when I owned them. I believe that since it took 16 days from the date they were delivered to open a claim that he knew they were beat, but didn't know what he was getting into when he bought them since they had some separation issues, and now wants a return. Anyways, I don't want to allow a return unless I have to so I though I'd check here before doing anything. Can you guys please check out the pictures below and tell me what you think? Thanks in advance for any help.
