Apple MacBook A1534 12"  MF855LL/A (Early 2015)
from original owner.
I purchased this computer August 2015 from Apple to be used while traveling.  It has been used approximately 20-30 days each year since.  Keeping it plugged into AC all the time at home, the battery stopped holding a charge for more than 2 hours and was replace by Apple about 2 years ago.  It now holds the full charge for approximately 9 hours as per specifications for this model.

The computer will be shipped in it's original Apple packaging including the original box, with power supply.  It is virtually  indistinguishable from new. This computer has the same amount of ram 8GB and an SSD of 256GB capacity as an entry level $1099 M3 13 inch Macbook Air.  Comparing it to the 13" current Macbook Air, there is little advantage in screen size as far as I can tell.  This computer will do most of the things a new M3 Macbook will do, only slower, but it's a lot cheaper.
