The packaging for Fanwu Tea Office organic tea adopts the codes of postal mail as its key design language. The outside box is in the form of an envelope, complete with a small stamp, the ink of a postmark, and the romance of a lacquer seal. The design aims to appeal to people's nostalgia and enthusiasm for receiving letters by mail. The four inner boxes use simple, retro illustrations of animals in four seasons, along with Chinese poetry. The illustrations are stickers adhered to the kraft-paper box, reducing production costs and making the packaging more environmentally friendly.
