Personally this is what i would do Offer to refund him when they are returned if they arnt broke and he's trying to pull a fast one he isnt gonna send them back If they arnt broke and he breaks them in order to send them back it kinda defeats the point in buying them and he will lose out on the postage to return them to you if they are genuinley damaged then fairs fair get them back and issue refund try and claim from the carrier altho some wont payout for glass/ plasstic breakages I wouldnt Cry about it its one of them things if thats all you have to worry about then i want your live and your issues use it as a lesson in life learnt and move on
