Car Phone Holder Smartphone Stand for Cars, Car Navigation, Tablets Size: 9cm wide x 5cm high This is a non-slip car phone holder. I purchased this, but I'm selling one that I haven't used. The following is borrowed from the description: A non-slip smartphone holder is very convenient when you go out by car. Because it has a non-slip feature, it's a very convenient item that can be used not only in the car but also at home, when traveling, in the bath, and in places where stability is lacking. Made of silicone rubber, it can be used anywhere and can be washed with water if it gets dirty.
