Hironao Tsuboi has designed “Cherry Blossom glass” for Japanese company 100 Percent. It is handmade by Japanese artisans who are certified for creating traditional glasses, and they are called “Edogawa Dento Kogeishi”.
The bottom part of the glass is shaped like “Sakura” or a cherry flower, and it leaves a shape of “Sakura” after poring a cold drink due to dew condensation.
