Wooden Go board legs with "Heso" (center marker) & Go stone set - Natural wood, natural lacquer, high-quality

Wooden Go board and black and white stone set.

Thank you for looking.

As an amateur, I am unsure of the material, but this is a set of a wooden Go board and Go stones.
Those who know the material will likely be able to tell.
The dimensions are:
Length: 45.5 cm
Width: 41.5 cm
Board thickness: 11.0 cm
Height: 23.0 cm
Leg height: 12.0 cm

The Go stones are:
White: 180 stones (I have one extra if minor chips are acceptable)
Black: 186 stones

There is a slight indentation of about 5mm on the 10th photo, but overall the condition is good.
