Liberty Hardware originally introduced this line of art glass knobs at $16.00 in an attempt to reach a high end customer base. They were low volume sellers. Imagine that -- a small number of people who can afford a sixteen dollar cabinet knob. Hmm-mm. So, we were able to purchase these at a great price and can now sell you an exquisite designer glass knob at an affordable price. This is the kind of deal we love to find and pass on to our customers. Gem Lilly Knobs were conceived to be part of a "step-up" category of products and are designed to appeal to fashion conscious buyers. These design conscious collections blend impeccable style and dependable performance. These knobs feature a combination of a naturally inspired metal base design and a beautifully cast jewel of solid Tiffany style glass. Diameter: 1 1/4" (31 mm) Projection: 1.12" tall (28.45 mm) Color/Finish: Amethyst Glass & Black Base Comes with mounting screw suitable for most applications.
