[About the "Triangular Nanjiang Stone" Variety]

The Nanjiang Stone is widely considered the "King of Density" in the Wenwan world, and the Triangular mutation is one of its most sought-after forms.

• High-Density Bone: Known for its extreme hardness and stone-like weight, providing a solid feel that is unmatched by other varieties.
• Triangular Geometry: This natural mutation creates three distinct sides, offering a specialized ergonomic grip and a unique visual profile compared to standard rounded varieties.
• The Concave Base (Ao Di): The natural recession at the base allows the walnut to nest comfortably against the palm, providing exceptional stability and control during rotation.
• Intricate Ant-Pattern: Features the iconic fine, dense rippling known as "Ant-Pattern" (Ma Yi Wen) that provides an intensive and therapeutic hand massage.

• Synchronized Structural Flow: The three-sided architecture is consistently matched across both walnuts, ensuring a uniform tactile experience.
