I am happy to offer these ready to ship set of 4 flamework glass knobs for cabinets, drawers or other projects. Each 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 Knob: 22mm/ Height of Knob 36mm/ Surface natural shine/ Metal oil rubbed bronze/ Number of Knobs included in set 4. This transparent globe of glass contains moretti glass in deep topaz color with earthy bits of pulverized glass melted in during production. They are encased in a super clear glass to magnify the impact.These are ready to ship and one of a kind. The variation of color makes them perfect for a gourmet kitchen.Thank you for your interest
