Dark blue (cobalt) glass cabinet knobs are perfect for kitchen cabinet door knobs, furniture drawers, bathroom vanities, dressers, and restoration of vintage furniture. Made from the finest silica glass and were individually hand made by professional glass workers. Measure 1 1/4 inches (32 mm) in diameter (measured from point to point on the hexagonal) and they have a projection of 1 1/4 inches (32 mm). Sold individually and come with the 2 1/2 inch Chrome mounting hardware. If you desire a flush finish on both sides of the cabinet - we suggest the use of Chrome or Brass caps. These metal caps fit into the glass - allowing the bolt to be screwed in from behind - providing an identical look and a flush finish (shown in the photo below).
