This is a car baby room mirror that attaches with straps. It attaches to the headrest of the second seat, allowing you to check on your baby from the driver's seat using the rearview mirror. [Product Description] You can check on your baby, who is sitting rear-facing, through the rearview mirror, providing peace of mind. It's easy to install, and the mirror angle is adjustable! [Size] Length: Approximately 17.5cm / Width: Approximately 24.5cm Made of shatter-resistant acrylic material, so even if it breaks, it won't shatter. It was used for about 3 months, but there are scratches on the mirror surface. There are also remnants of the film. I think it doesn't affect usage, but please refrain from purchasing if you are concerned. Please understand that this is a used item before purchasing. It will be shipped in a cardboard box. Thank you for looking. Insight Mirror Room Mirror Rearview Mirror Child Seat
