High quality cased glass is notoriously difficult to make, due to a very high rate of breakage. We've been lucky enough to partner with a small studio that works in the traditional method of blowing one color inside of another in order to achieve the cut-through effect shown here - at a reasonable price. We offer three patterns, each in its own custom color combination and variety of unique silhouettes. The 'Channel' pattern in amethyst and aquamarine is offered in four silhouettes.
