KANNA GLASS by Hiroshi Yamazaki

Designed by Hiroshi Yamazaki of YAMASAKI DESIGN WORKS, a Japanese original brand. Using a woodworking tool called "Kanna," a cone-shaped prototype was carved to create the design of a glass cup. The bottom of the cup features an irregular cut surface, making it impossible to lay the cup completely flat, and the appearance of the cup will change depending on how it is placed.
