The postbox is designed in the shape of the "Bargibant's pygmy seahorse," a precious species unique to Taitung's waters, known as the "little marine elf of Green Island." It is highly favored by divers worldwide. Nearby, the "Heart of the Ocean" artificial reef has been installed, making it Green Island's most popular and unique photo spot.
