Bad move--- if something should go wrong you will not have a leg to stand on. What's to say you send buyer money for some reason instead of refunding, The transaction does not correspond with any ebay transaction. The buyer opens a item not described or not received and claims a refund. Because you don't have proof of the send money being for that ebay transaction paypal would most likely refund the buyer. You are then out of 2 lots of funds.
