If you put a lid on the spouted vessel, it becomes a "treasure pot." If you put a lid on the bowl, it becomes a "covered bowl." With just this, you can enjoy authentic Chinese tea. Pour tea from the covered bowl into the spouted vessel, then place the lid of the covered bowl over the spouted vessel. This allows you to keep the remaining tea warm. I think this feature, which I invented myself, is revolutionary and quite delightful. The more you use it, the more comfortable it feels, making it an indispensable tea set. Particularly, the feel and pouring experience of the spouted vessel are unmatched by any other. Because it can be stacked, it fits compactly in your cupboard, making it ideal for travel. You can store 2 or 3 stackable V-shaped tea cups, made for the treasure lid. You can enjoy your usual taste even when traveling. The flavor is aromatic, so you can fully enjoy the top notes of the fragrance of Taiwanese tea. Since it was released about three years ago, cumulative shipments have exceeded 1,000 units. I am happy that the circle of treasure lid lovers is steadily expanding. This is a set of three pieces: bowl, spouted vessel, and lid, with a box. Tea cups are sold separately.
