Listing is for 1 each 923-0439 sealed in an anti-static bag. I've got 5 at start of sale. I opened 1 of them to get good pics and made sure it was properly handled and returned to the bag. Got these recently from a friend that was storing stuff in our building. I don't know much about compatibility with these Macbook parts so take a good look at the pics & if you have any questions or input don't be afraid to message me. The box in the pics is the box they were in when I got them. It will be shippedUSPS PriorityMail. I usually ship within 24 hours ofpurchase.
