The fountain pen with beautiful metal processing entrusts the design with the thought of protecting endangered species. "The design is based on the "Taiwanese black bear", "foot swallowtail" and "Bengal wildcat", which live only in Taiwan and are designated as endangered species.

According to a report by the World Wildlife Fund (WWF), the diversity of the Earth's ecosystems has decreased by 68% over the past 50 years, and humanity consumes 1.6 times more natural capital than the Earth produces in one year. Global warming and overexploitation caused by carbon dioxide produced by mass consumption have narrowed the habitat of wildlife, and their populations are decreasing year by year. Protecting their lives can be said to be the mission of us humans.
