Sylvain Willenz: “This Japanese soda bottle is part of my small collection of glass objects. While visiting a temple in Japan, I bought a drink at a stall and was amazed by the bottle. Although usually consigned, the stall owner gave it to me. It is surprising because the bottle is sealed by a glass bead, which one manually forces inwards to open it. One should drink holding the bottle with the two dips pointing towards him/her; this will prevent the bead from rolling back and closing it as you drink. The bottle is used again and the bead also seals it over and over.”
