This is a baby mirror from Toys "R" Us. You can check on your child through the rearview mirror, and your child can also see their own face, so even when they're in a child seat, they won't get bored and will stay well-behaved. It's easy to install, just attach it to the headrest. The overall size is approximately 21cm in height and 31cm in width. I no longer need it because I've switched to a forward-facing child seat. There are some scratches on the mirror surface as shown in the pictures, but I think it can be used without any problems. There are no instructions. The mirror has been home-cleaned, but it is a used item, so please understand this before considering purchasing. #BabyMirror #ChildSeat #BabyInsightMirror #BabySafetyMirror
