These are sturdy and so easy to use. Easy to install, a small screw driver required. 4 Pieces plus 2 screws for each lock. We recommend using Lock tight to keep screws put in place.
The Iridescent Rainbow color varies for each piece and none of them are exactly alike. You may get a label that is more pink, purple, yellow or blue, etc., because they are all different. They don't change color, but have the look of iridescence.
