From Bull in China: These gorgeous glasses are just as functional as they are beautiful. This premium glassware is handblown in the Pacific NW. We think this one-of-a-kind glass bridges the line between high end equipment and functional art. It will surely become your favorite (if not only) mixing glass once you see it in person. They're incredibly durable, made to handle huge temperature swings without cracking, and have a smooth, seamless interior (a necessity for any quality mixing glass). The exterior pattern is naturally occurring from the glass cooling, so no two are alike. Liquid capacity is ~22 oz / 650ml. Works with a standard julep strainer or Hawthorne strainer. *Because of the handmade nature of this product, there may be slight variations from glass to glass. We like to think this adds character.
