I drew a mathematical expression in a plump big cup.
It is good size for tea and coffee.
Bore size (in wide area) 8.6 cm, height 10.3 cm
Appropriate capacity of about 330 cc
You do not need to start using it as it is. (It has been treated with liquid ceramic) Still it will be slightly soiled so it is better if you can cook it with rice soup of rice.
