This special collaboration has been realized between "Sora Jiro," who has conveyed the changes of nature and the importance of the environment through weather, and "Tunk Tunk," a curious spirit who came to Earth from far beyond the universe, longing for our planet.
In this collaboration, in addition to standard items such as acrylic keychains and clear files featuring both characters adorably side-by-side, unique items specific to GREEN×EXPO 2027 will appear, such as "natural wood stickers" and "natural wood postcards," which offer the warmth of natural materials. We plan to continue developing a rich variety of collaboration items that leverage the charm of both characters. Please look forward to future updates.
