This is the Quick Corner Caddy TM system. It includes a 8" natural stone shelf of your choice, mounting bracket, glue, sandpaper, wipes, and instructions all in a beautiful package. With this system you can easily mount a natural stone corner shelf in a shower that is already tiled. It is the best alternative to the aftermarket metal shower corner shelf system that will rust or corrode. Please select the color and quantity you want with the drop down box (COLORS ARE IN ORDER FROM LEFT TO RIGHT IN INITIAL PICTURE IN ACCORDANCE TO THE DROP DOWN BOX - IVORY, WALNUT, NOCHE, HONEY, AND SILVER). If you want it polished on the underside select the option from the list for underpolish.
