Each bud vase is entirely mouth-blown by skilled Japanese glassblowers, and will vary slightly in shape.  Place a single stem flower inside, display a dry leaf. or simply have the glass bud vase stand alone and enjoy its sculptural, natural stone-like shape.  These vases are made of pure black glass that has been created by mixing together many different colored glasses - it is not coated to achieve it's lustrous, shiny, opaque appearance.
