Brand new Sealed AP Biology Flashcards by McGraw-Hill. I bought these as a gift for a rising senior and he already had some, so I am passing these along to some lucky bidder! If you have any questions please email me. Be sure and check out my other auctions! Paypal is payment method. All items are smoke and pet free. I package all of my items with care, and if an item is breakable I ship it in a box, never in an envelope—if it is not fragile, it will be folded and placed in an envelope. I am not an authority on anything, and am human, so if you have a question please ask–I may not know the answer but will try to find out. Only items grossly misdescribed may be returned, all items subject to 15% restocking fee. Items returned used or that are no longer in mint condition subject to 50% restocking fee–no exceptions.
