Very pretty design. Square knobs require perfect alignment and leveling. These have a tiny spike on the back that is impressed into the cabinet door to help keep the knobs from spinning and getting out of alignment. I paired these with the matching pulls, and it makes a clean but elegant look that can work with transitional, traditional, or contemporary decor. I like the design along the edges. On my polished nickel though, there are some little textured areas in those grooves. They don't show up in the same style in satin nickel. Would and did buy again.
