Brand new, still in the bag (opened to photograph)is a low flow showerhead. The back of the tag has the installation & operating instructions on it. It says that if you can change a light bulb, you can install this money saving showerhead. It just screws into place and they ask that you do not over-tighten when you do. The push button cut-off valve allows the user to cut the flow of water to a trickle when soaping up. This makes it un-necessary to re-mix hot and cold water when the full flow is restored. The showerhead is made of metal and measures about 3 1/2 inches long. The bell is 1 1/4 inches in diameter.
