Nice shower organizer mountable without drilling. Only 2 x M5 screws needed to screw the two parts together on the standard shower holder. Width is 100 mm (~4 inches) so it can handle almost every size of shampoo or shower gel . The small seperated area is siutable for razors / shavers and other small stuff used in shower. The printed hook in the side is perfect for holding a washcloth or a wiper.
