Our Alegre Collection is a whirl of color and movement. These glass knobs will brighten up any space. Formed using a flame from a special torch, it takes great skill and patience to create each knob. The colored swirls of glass are added to the outside of the knob while it is still very hot. You will enjoy this durable new art form in the knobs from All That Glass. We can create many colors in this design, just contact us and we will work with you to create the look you want. Custom work is our specialty. Every glass knob is shipped with: 1 center pin, 1 1 ½" X 8/32" screw, 1 rubber 'O' ring, and 1 rubber washer.
