This is the “Snow Grade / Blossom Grade Go Stone Grain Pattern Sample Set,” which allows you to compare the grain (striations) of Clamshell white Go stones in both Snow Grade and Blossom Grade.

At present, our “Clamshell Go Stones Premium Snow grade” and “Clamshell Go Stones BLUE Label Snow grade” are available only in limited quantities, and some sizes are already sold out.
Because a full set requires 182 stones of the exact same specification (quality and thickness), it is extremely difficult to replenish inventory promptly.
We kindly ask for your understanding.


To help customers compare the grain patterns (striations) of Snow Grade and Blossom Grade clamshell white Go stones when considering a purchase, we have created the “Snow Grade / Blossom Grade Go Stone Grain Pattern Sample Set.”
This set allows you to examine a total of 14 stones: seven Snow Grade stones and seven Blossom Grade stones, in seven different sizes ranging from Size30-42.

In the past, many customers have told us : “I want to purchase Clamshell Go stones, but I’m not sure how Snow Grade differs from Blossom Grade,” and “I’ve heard Snow Grade stones are beautiful, but I’ve never seen them in person.”
We also want our customers to clearly confirm the differences in grain patterns and to experience firsthand the natural beauty of Snow Grade stones. For that reason, we are releasing this Snow Grade / Blossom Grade Go Stone Grain Pattern Sample Set.

This set not only lets you compare the grain pattern differences, but also allows you to experience the smooth texture, cool touch, refined beauty, and satisfying weight of genuine Clamshell stones—each piece carefully crafted by skilled craftsmen.

This is a good choice for those who are considering purchasing Go stones as well as for your collections.
It comes in a compact wooden box measuring 177 mm (length) x 80 mm (width) x 37 mm (height).
