These are rubber covers to hide the screw holes that come with ALPINE flip-down monitors. The set includes black and gray colors. (The black is not pure black, but a light black.) These are new, unused items that have been stored. They are compatible with all Alpine rear vision models, but please check the size just in case. The diameter is approximately 17.5mm. There may be some dust or small debris that has accumulated during storage. Please refrain from purchasing if you are sensitive to this. The photos are reused. We are sorry, but these are sold as a set of 2 pieces of each color, so we cannot offer a half-price option for one piece or color changes. Please purchase only if you need them. We will not be offering any discounts. Thank you for your understanding. #RXH12X2-L-B #TMX-R2200 #PCX-R3300 #PCX-R3500 #TMX-R3200 #TMX-R3000
