Marble Go Game Set (White/Black) - Material Unknown, Heavy Feel

Selling as part of decluttering.

■ Product Condition: This is a set of go bowls and go stones featuring the beautiful pattern of white marble.
It belonged to my aunt, and while I don't have detailed information, it was carefully stored.
■ Material Disclaimer (Please Read Carefully): As I lack specialized knowledge, I cannot definitively identify the exact materials of the go stones and bowls (e.g., natural stone, ceramic, glass).

Texture: It does not have the lightness of plastic; it has a substantial weight and a smooth texture like pottery.
Appearance: The white stones do not show the characteristic striations found in shells.
Material assessment is subjective, so please purchase only if you can make your own judgment based on the provided photos.

■ Condition: The marble containers may have patterns unique to natural materials and minor scuffs.
While each go stone has not been individually inspected in detail, no significant cracks are apparent.
As these are old items, please understand they are vintage and used.

■ Contents:
Marble Go Bowls with Lids × 2
Go Stones (White & Black) *The exact number of stones has not been counted, but there are enough to fill the bowls.

■ Shipping: Due to their considerable weight, they will be securely packed with cushioning material to prevent breakage and shipped via Raku Raku Mercari Bin.

Returns will not be accepted due to the prevention of fraudulent exchanges or misunderstandings about the materials.
