Justice cup is also known as serving cup or tea sea. It is used for uniform tea concentration. There are three types of justice cup.
- Pot shape cup: Use a teapot instead.
- No handle cup: The pot handle is omitted. In order to distinguish it from the pot, the mouth of the pot is often pulled out into a flange instead of pouring the hand.
- Simplified cup: No cover, pull out a simple pour spout from the body, with or without a handle.
In addition to the uniform tea concentration function, the tea stalks preferably have a filter residue function.
