11/10: New - Factory Sealed Shipment Items classified as "NEW" must be in a factory-sealed box. Sellers must specify any manufacturer warranty included. Some manufacturers honor warranties only if purchased from an authorized dealer, while others limit warranties to the original owner, even if the item remains unopened. Any "NEW" listing should include a warranty statement. If absent, buyers should confirm details with the seller. Assumptions should be limited to the item being factory sealed.

Items opened for inspection or any other reason should not be rated as "New."
