This item was given to me about 30 years ago by a relative who was a calligrapher. I've kept it at home ever since, but I have no plans to use it, so I'm putting it up for sale. I will take it out of the box for shipping and package it. Length: 9.5 cm, Width: 2.5 cm x 2.5 cm I have no knowledge of the material the seal is made of, but after doing some research, I believe it may be Shoushan stone. Very fine inscriptions are carved on the sides of the seal material. I believe it is a valuable item, but I think the demand for it has decreased nowadays, so I have set the price accordingly. Returns are not accepted after shipping. Thank you for looking.
