400-MA128 Touchpad Trackpad Wired, Slim Gesture Function, 400 Count Purchased about 1-2 years ago and stored in a dark place after a few uses. Instruction manual and box are not included. Also, the cable is probably not the original one. I have confirmed the operation and it works, so there should be no problem with use. There are some scratches to the extent that they do not affect use, so please purchase with your understanding. Instant purchase is also possible. Thank you.
