Thank you for viewing. I am selling this because I bought it but haven't used it much. This is a used item, and by purchasing it, you acknowledge and accept its condition. Please check the condition in the images. The following is a reference from the original purchase: 【Enhanced Radio Wave Blocking, Compatible with the Latest Cars' Strong Radio Wave Smart Keys】 This product can completely block radio waves even from the latest cars with strong radio waves, such as Lexus, so you can use it with confidence regardless of the car model. Unlike the cheaper 1-2 layer structure products, this product adopts a luxurious 3-layer structure design with high-quality radio wave blocking fibers, completely blocking radio wave leakage and hacking. High-quality radio wave blocking material produced in a specialized factory with strict quality standards. It has cleared three quality tests: interference test, interlocking test, and detection test, ensuring reliable car theft prevention! 【Excellent Durability, High Durability with Anti-Oxidation Surface Treatment of Radio Wave Blocking Fibers】 Untreated radio wave blocking fibers are prone to react with moisture and oxygen in the air, causing the surface to discolor and corrode, and thus lose their radio wave blocking ability. The radio wave blocking fibers of this product are protected by a film made with anti-oxidation surface treatment, which is generally rust-resistant and has good corrosion resistance, so the radio wave blocking performance does not deteriorate even after long-term use, making it perfect for relay attack countermeasures! 【Compact Size for Easy Carrying】 Unlike products with larger sizes, this product achieves a convenient compact size of 8.5 cm wide x 13.5 cm high, and it fits in your trouser pocket, making it easy to carry around. 【Compatible with Almost All Car Smart Keys】 Compatible with remote keys and card keys of Mercedes-Benz, Porsche, Lexus, Honda, Toyota, Nissan, Mitsubishi, Mazda, Subaru, Suzuki, VW, Daihatsu, Citroen, BMW, Alphard, Mini Cooper, Prado, etc. (Due to the compact size, there is little space, so please remove the smart key cover/ring before putting the key in the case.) 【Horizontal Design, Easy to Put In and Take Out】 Unlike vertical pouches, the horizontal design has a wider width, making it easier to store from the side. The button is also magnetic, making it easy to put in and take out! It has a hook design for wall hanging, and it also comes with a string to prevent the smart key from falling out, so you can use it with peace of mind.
