Calligraphy Supplies Chinese Huizhou Ink Old Ink Unused Item

This is an unused item of Chinese Huimo ink.
I am not knowledgeable in this area, so I do not know much about this item, but it is an antique item owned by my parent who practiced calligraphy.
The outer box shows its age due to the passage of time (no noticeable stains or damage), but the ink itself appears to be unused and free of scratches. Please judge from the photos.

Outer box dimensions: Width 9cm x Height 17cm x Depth 2.5cm
Ink body dimensions: Width 6cm x Height 14cm x Depth 1.6cm
Ink weight: 208g
