I am happy to offer these ready to ship set of 7 flamework glass knobs for cabinets, drawers or other projects. Each glass knob is hand made over an open flame, and annealed in a digitally controlled kiln for strength and durability. Following the annealing, glass is cleaned and affixed to a metal component. Mounting hardware is included so upon arrival these items are completely ready to install. Set specifics: Diameter of disk: 31mm , Thickness of disk: 9mm, Finish of hardware: oil rubbed bronza, Total depth of knob and hardware: 25 mm, Finish of glass; acid etched These are ready to ship and one of a kind. Thank you for your interest. These are opaque and swirled in a tapestry of speckled colors. They would be right at home with a beach theme or just to help create a little getaway.
