This is an item from the estate of my grandmother, who practiced poetry (Chinese poetry) and calligraphy. I am not familiar with the value of ink and brushes. I believe the white ink is rare, as these are the only two I have. One has been used. It is unclear whether the other has been used. I believe they are old, but their origin is unknown. Please check the condition. The box is not the original box for the ink, but it was empty, so I will ship the ink in it. Please purchase only if you understand that these items have been stored at home and have been inspected by an amateur. Thank you for looking.
