Tea Turnbler / Tea Tumbler

Tea Turnbler
Tea Turnbler

"Tea Turnbler" is a tumbler solely designed to provide an authentic oriental tea experience to users. The design concept of "Tea Tumbler" was inspired from the traditional way of serving tea in Asia, thus it shaped like a traditional Korean porcelain.
"Tea Turnbler" enables easy and iterative brewing simply by just turning it over. It also enables users to feel the rich moment of tea-brewing by visual stimuli. When "Tea Turnbler" is turned over and starts brewing, light from the LED inside the cap is diffused throughout the tea-brewed water, and expresses the color of tea-brewed water through the transparent parts of "Tea Turnbler".
