This is an ultra-large wooden go bowl made by skilled Japanese craftsmen, crafted from zelkova wood. It can store all types of glass go stones, while accommodating clam stones up to size 45 (approximately 12.8mm in thickness).

The zelkova wooden go bowl features a rich brownish color and well-defined wood grain, making it a popular and classic choice for storing clam go stones.

The lid of the go bowl is designed with a slightly elevated rim (tamabuchi) for easier handling when removing the lid.

The zelkova go bowl develops a deeper color over years of use, enhancing its luxurious feel, making it a highly recommended wooden go bowl.
