This is my classic beach glass knob. It was created in 1996 and it traveled the Eastern seaboard of the United States with me as I made my way as a designer/artist.doing outside art fairs. It is hand carved and tumbled to create a natural beach glass feel. It measures 1-1/2" square by 1/2" thick and is mounted on a non tarnishing brushed aluminum 1/2" square base. It extends 1" from the surface it is mounted on. These following bases are also available. A round satin nickel base that measures 5/8" and is also available in chrome, shiny brass, and hand rubbed bronze that looks almost black. The wine glass base measures 3/4" high. It comes in polished nickel. Custom sizes and rectangular shapes are available on request. Colors can be ordered by numbers and letters on the color chart.
