To to celebrate the cubs' grand debut, CSTB, HKTB, and Hongkong Post are introducing 3D panda mailboxes. Each postal box will show the 3D-printed giant panda twins ready to greet the public. Elder Sister holds a soft ice cream in one hand, while the Little Brother grabs a camera, seemingly prepared to capture the charm of Hong Kong. A total of 49 panda-themed postboxes will be installed throughout Hong Kong from February to March.
