Windshield wiper blades
Size: 24" + 19"(Pair for Front Windshield Lock)
Easy to install and fit perfectly on our 2023 Honda Civic sport. Good quality for a brand that is much cheaper than buying from the local auto parts store store. The last pair of these lasted a few years in the Florida sun so they are durable. The clean the windshield well and leave it streak free
