Start button cover, red 08161-K2002 DAIHATSU Genuine Accessories Diameter measured: Approximately 29mm, slightly larger Used on the engine start switch of an ND Roadster. As it is a genuine product, I believe the quality is assured. The surface is clear and a beautiful red. There are some minor scratches that are difficult to see in the images, but I think they won't be noticeable once installed in the car. Adhesive remains on the back, so it might still work as is, but please consider adding double-sided tape. Thank you.
