The concept of this package design comes from movable metal type. In the beginning, we came out with this idea from the shape of tea bricks. Movable metal type and tea have a long history, and both of them reflect our ancient culture. The characteristic of tea bricks is that it takes a long time to make a tea bricks, and only the highest quality of the tea can be made into tea bricks for preservation of a long time. In addition, the flavor of the tea gets rich as time goes by. Just like the processing of casting the metal type, it takes time and effort in a high temperature environment. That is the reason why the tea tastes full of aroma.
