[About the "Qishan" Quad-Ridge Variety]

The Qishan variety is revered for its wild, unyielding character and its exceptionally hard, high-density bone quality. The Four-Ridge mutation represents one of the rarest biological occurrences in the walnut world.

• The "Cross" Apex: Unlike standard walnuts with two ridges, this mutation features four primary ridges that intersect at the top to form a perfect cross. Achieving this level of structural symmetry in a wild variety is statistically improbable, making it highly collectible.
• Complex Tactile Geometry: The four-ridge structure creates four distinct "valleys" for the fingers. This provides a multifaceted tactile track that offers unparalleled grip and a highly engaging rotation experience.
• Wild Origin Resilience: Qishan walnuts are known for their deep, winding "wild" textures. They are incredibly durable and produce a sharp, metallic "clinking" sound that signifies elite material maturity.

[Characteristics of QSSL-1201E]

• Impeccable Structural Symmetry: The cross-shaped apex on both walnuts is centered and crisp. This ensures a balanced, uniform feel in the hand, allowing for smooth, rhythmic manipulation.
• Rugged Wild Texture: The surface is rich with the deep, winding folds characteristic of the Qishan variety. This provides a rigorous hand massage that effectively targets the palm's pressure points.
• Perfect "Shou Nian" Proportions: At 33mm wide, this set is designed for "all-day" rotation. It fits discreetly in the hand while providing the complex tactile feedback of a much larger specimen.
• Premier Patina Potential: Hand-selected for high density and uniform maturity. As these walnuts absorb natural oils, they will transform into a deep, translucent mahogany-red that highlights every intricate detail of the four-sided frame.
