Island glass was inspired by Korean islands, Dokdo and Ulleungdo. The inspiration came from the bottom of the glass after viewing the flipped-down soju glass on the table. Soju is the most popular Korean liquor. The glass shape consists of a streamline based on the shape of the Korean language at the bottom of the glass. The shape engraves an image of a floating island on the ocean when the Island Glass is displayed. The material consists of an unleaded crystal that expresses clear texture and delicate details and at the same time manufactured harmlessly to the human body and environment.
