Easy to apply just by sticking them on! I've confirmed the size on actual cars at car dealerships, so please see the list below. Toyota: Alphard, Vellfire, Sienta, Corolla & Fielder, Prius, Prius α, Harrier, Estima, Aqua, Noah, Voxy, Esquire, Roomy, Tank Daihatsu: Canbus, Thor Suzuki: Wagon R, Stingray, Lapin, Spacia Custom Mazda: CX-3 Honda: Freed, Fit, Step Wgn, Vezel, N-WGN, N-BOX, N-VAN, Odyssey Regarding the old N-BOX, the size is okay, but there will be a gap because the push button area of the car body is not flat. It is possible to use them around the air conditioner. Ring size: Approximately 3.9cm in diameter, 3cm inner diameter. If the size fits, it will work on unconfirmed car models as well. Perfect for those who like decorations, such as Garcon, DAD, and glitter rings, etc. Please check the size as there may be differences depending on the year and model. <(_ _)> You can purchase immediately without a comment. #Car Interior Accessories
