This is a charger compatible with MacBook Air and iPad Pro. I've used it for about a year, but there are no noticeable scratches or stains. Please note that this is a used item, so no returns or refunds are accepted. ※ From the Apple official website: The 30W USB-C Power Adapter allows for fast, efficient charging at home, in the office, or on the go. While the power adapter is compatible with any USB-C device, Apple recommends pairing it with the MacBook Air. You can also use it with some iPhone and iPad Pro models to take advantage of the fast-charging feature. Charging cable sold separately.
