ALOHA! This original catstudio glass design celebrates the beautiful State of Hawaii and its beautiful islands and Spirit of ALOHA. Carmel Swan, one of the owners of catstudio, is a native of Hawaii and she worked long hours to make sure it's a beauty!!! And it is!!!The catstudio glass tumbler design is amazingly rendered with seven lead-free colors plus matte gold on a high quality 15-ounce frosted tumbler. Cheers and bottoms up! Dishwasher Safe.
