Cosmetically considered as grade (B) expect to see light wear such as light dents, and keyboard markings on the screen or minor scratches. all of the units are 100% fully functional with no issues, batteries have 100% health! all of the units have a little pinhole chip on the screen, but nothing serious! if I didn't mention it you wouldn't see it! macOS 'Monterey" is currently installed, though feel free to request a different OS at checkout. overall in very good shape! it has been tested and cleaned! the pictures represent all the units we have from the same grade, please see the pictures for any cosmetic condition!
