Sink Caddy
Color: Gray
It looks good on back of sink but would be more efficient if it were 1/2 an inch deeper. As it is, it doesn't have enough stability and tends to move about, therefore excess water may not run in sink as front edge doesn't pass over sink edge.

Works out great for the sink in my camper. It holds everything I need and takes up very little room.
