What bothers us about most door knob sets you find in the stores today is that they are either plastic or made from the lowest quality zinc alloy. They break and lose their luster overnight - and they look cheap even from a distance. This Black Porcelain door knob is made from real porcelain and top quality brass and steel components. Moreover, it is flexible. The parts are interchangeable so you can replace different knobs and back plates to update your look in the years to come without replacing the entire knob set.
