I received these a long time ago from a relative who used to run a calligraphy class. One has a "Dengkei" (端渓) trademark sticker, so I believe it's a Dengkei inkstone, but I'm not sure. I have no idea where the other one is from, as it has no sticker. The wooden lid doesn't close tightly (even without the inkstone inside). My relative told me they were expensive, but I don't know for sure. They are old, so please understand that there is dirt, dust, and scratches. I am not considering selling them separately at this time. Please feel free to ask any questions in the comments. Thank you for considering purchasing these.
