This is a tested and initialized MacBook Pro. I have been using it as a sub-machine in recent years. I think it's clean because I used it in clamshell mode with an external display and external keyboard. I have done home cleaning, but there is some sticker burn on the exterior depending on the light (see photo 3). Also, there is a 5mm wide dent on the back (see photo 4). Please refrain from purchasing if you are concerned about the above two points. Also, please read my profile. The original box will be wrapped in cushioning material and then shipped in a cardboard box with cushioning material. It will be shipped via either Rakuraku Mercari or Yu-Yu Mercari.
