Intentionally irregular and random is the concept of this uniquely tilted glass tumbler. This glass is created as a collaboration between a designer, Hiroshi Yamasaki, and a Tokyo-based glassware company, Kimura Glass. The tumbler is designed so it can comfortably fit in a hand, and the bottom is shaved with a plane after the glass' initial shape is made, so that the bottom resembles a surface of a rock and the tumbler can sit at different angles. The name "KANNA" comes from a Japanese word for a plane. At a first glance, the glass looks almost unstable sitting at an angle, but it is carefully designed so it can sit comfortably. Whatever drink you enjoy with this tumbler, we hope this will give you a special experience each time.Hiroshi Yamasaki, A product designer. Born in 1970 in the city of Kobe.
