This is a set of 3 chrome mirror covers for the Nissan 31 X-Trail. Includes 2 for the left side and 1 for the right side. These are not genuine manufacturer products, and are likely generic products made in China, but they have a good chrome finish and the fit isn't bad. (This is a personal opinion.) Double-sided tape is included, but the adhesive is weak, so additional tape is recommended. Thank you for looking.
