These "Cu Tao" clay cha hai were fired in wood burning kiln. Being porous these can be seasoned and dedicated for a certain type of tea. Would be best suited to Raw Pu-erh, Oolongs or Black tea, but could be used for any type of tea. If you don't want to dedicate it for just one type of tea you can just rinse well in-between sessions.
Each piece is unique and may differ somewhat from the pictures!
Volume is 160ml (+/- 10ml)
