It is a new work of rock glass. The design is "whirlpool".
 The image of the whirlpools of large swells swirling on the surface of the sea, the splashes of the violent river currents, and the swells of the water makes you feel the rich capacity of nature.
 Rock glass is a versatile glass. We would appreciate it if you could accompany us with a relaxing time such as alcohol and soft drinks.
 Caliber 7.7 cm, height 9.2 cm.
 In addition to the green color in the photo, purple, lapis lazuli, and red are also available.
