Thank you for viewing. Finalmouse UltralightX PRO TARIK This is the exterior. Size is M. In addition to the inherent yellowing, there is color transfer from arm cover use (there are black marks in the 7th photo). Please note that there is no base for installing the circuit board. The grip tape is unused. The original box is also included. As a bonus, I will include a third-party wheel. It is easier to operate than the original. This is almost new.
