This is a 12-inch gold MacBook with a Japanese keyboard. I purchased it used and had the battery replaced with a new one immediately after, and I've been using it for about a month. It works without any problems. The exterior condition isn't very good, so I'm listing it as junk. Please check the photos. I've confirmed that all functions work, but I am an amateur, so there may be oversights. Please understand. It has been initialized, the OS is Big Sur, and the password is: 0000. It will be shipped as is. - Model Name: MacBook 12-inch, Early 2015 - Color: Gold - Keyboard: Japanese layout - Screen Size: 12 inches Thank you for looking.
