Cute soap and sponge caddy
Color: Black
Good product! I like how the water drips down into the sink. Instead of on the back of the sink. Helps keep the area cleaner and dry.

Aesthetically pleasing to the eye
Color: Black
This product is a good organizer for the song it serves its purpose. However I wish the tray that catches the water would stay in place. It is constantly moving and doesn’t always tilt to allow the water to flow down properly. The quality of the basket is good. It is easy to keep clean. It was super easy to assemble did not require any special tools. So far so good it is withstanding being wet all the time and I do not see any rust or deterioration or fading of the color in the two months I’ve had it. This sink organizer is modern and adds a nice aesthetic to my kitchen.
