10 pieces arrayed two-dimensional clouds are displayed in the transparent box.  Each piece cloud is tied a tea pk at the bottom . The piece cloud is easy to extract, and there are two bayonets on the cloud to be fixed in the inner packaging structure. At the same time, the card can be drawn out and stuck to the cup mouth. Cloud is a non artificial form and is purely natural and organic. This property matches the organic, natural and healthy attributes of tea.
