The Moorgen Wall Knob is a compact, multi-function rotary controller that can be used to control lights, music, curtains, and more. By pressing the light indicator button, you can adjust the brightness of the light by rotating the knob. The shape of the knob is simple and round, and the contrast between the metal body and the black plexiglass gives the product more texture. With a variety of interior styles and colors, you can choose your favorite color and hang it on the wall wherever you need it.
