These Go bowls are wood craftsman Mr. Kawashita made Yakusugi Go Bowls with Oil Burl Tiger Stripe Grain for ~Size 40 Go Stones.
These Go bowls can hold Go stones up to size 40.

These Go bowls are crafted from "Abura-kobu / Oil Burl" Yakusugi (Yakushima cedar) wood, estimated to be approximately 2,000 years old.
"Kobu / Burl" forms when a tree sustains damage or undergoes abnormal growth, causing resin to accumulate and create a raised, knot-like structure.
Among these, "Abura-kobu / Oil Burl" refers to sections that contain particularly high amounts of resin and natural oils.
Yakusugi Oil Burl is highly prized for its exceptional beauty and is often used in the finest woodworking pieces.

Additionally, these Go bowls features a rare and exquisite grain pattern known as "Tora-moku / Tiger Stripe Grain", characterized by shimmering, striped patterns that change in appearance depending on the viewing angle.

Yakusugi, a type of Japanese cedar from Yakushima Island, is an exceptionally rare and highly valuable wood.
Since Yakushima was designated as a UNESCO World Natural Heritage Site, the logging of Yakusugi has been strictly prohibited, making it extremely difficult to obtain new material.
Its intricate and delicate grain possesses an elegant beauty that never ceases to captivate, attracting dedicated Yakusugi collectors from around the world.
Yakusugi is widely known as a premium material for tables and fine furnishings.
Due to its natural beauty and rarity, it is also highly valued as a material for Go bowls.
