what I should do.
It isn't for us to suggest what you should do.
We can tell you what you will have to do if your buyer opens a case under eBay's money back guarantee, which is to confirm your willingness to refund the buyer on the return of the item.
Assuming that you want it back, eBay will enable you to buy and send them a prepaid return label. If you accept the return this won't count against your seller performance rating, and when eBay has processed the buyer's refund you will receive a credit for your final value fee. (PayPal's fees are no longer returnable.)
If you dispute the case and lose, which you would, eBay will step in and enforce a refund. This would mean defect on your account, and you would forfeit any return of fees.
