Don't ship, contact paypal first, tell them whats going on, your concerns,,

What scammers do is claim the item was damaged or not as described and paypal has them send it back, once they show it's delivered back to you they get a refund,, problems is you get a box of rocks not what ever you sent.

Even using paypal as a seller you can get scammed,, I don't let new members with zero feedback buy from me using paypal,, I have them send money orders unless they have proven good feedback

good luck
