Karin瘤 is a burl (瘤材) that can only be harvested from a part of the root of the Karin tree, and has been popular as a material for high-end crafts since ancient times. It is very beautiful and valuable. Among them, genuine Karin瘤 often has complex grain patterns, and above all, it has a sweet scent! This one has a very fine grain and is highly recommended♪ It's a shame that the grain doesn't show up well in the photos... Because it is a burl, there may be chips or dents.
