This is quite old, having been stored with little use (used a few times). Judging from the inclusion of "Kanton Boki Kō" (Canton Inkstone Pit) paper, it is likely an Endeki inkstone. The stone color is magan-iro (horse liver color), and it exhibits stone patterns characteristic of Endeki, such as jade-like streaks and sugime (cedar eye) patterns. The first photo shows the inkstone surface wet with water. The inkstone's dimensions are: Length: Approximately 15 cm Width: Approximately 10.2 cm Thickness: Approximately 2.4 cm Weight: 919 grams As it is an old and used item, there are scratches and stains on the inkstone surface due to aging. The paper box has deteriorated significantly with age, showing stains, dirt, and tears. Also, as is common with old Chinese inkstones, there are original stone imperfections and shallow dents on the bottom of the inkstone due to the use of natural stone to its fullest extent in its creation.
