Hi , just wondering if anyone could advise.  My buyer says the gilet I sold has a tear on it asking for a return.

I'm sure there was not any damage on it. I've been buying-selling on Ebay for 15 years.

Never had any issue with buyers before. He sent me a pic of the tear.

 I checked the item thoroughly. 

Is there any way I can proof the item was not faulty?
