[About the "Sizuolou Half-Wall" Variety]

This specimen combines the legendary pedigree of the Sizuolou with a prized growth anomaly known as "Ban Bi" (Half-Wall).

• The Classic Sizuolou: Widely considered the "King of Lion Heads," Sizuolou walnuts are famous for their large, flat "Chrysanthemum" bases and deep, interconnected winding ridges. They are the premier choice for achieving a bright, porcelain-red patina.
• The "Half-Wall" Mutation: One side of the walnut developed naturally flatter than the other, resulting in a distinct "D-shape" or half-moon silhouette.
• Tactile Leverage: Elite collectors seek Ban Bi mutations because the flat side rests flawlessly against the palm or fingers. This creates a specialized sliding and pressing mechanic that offers more control and comfort than standard round varieties.

[Characteristics of SZLBB-1201E]

• Dynamic Sizing Split: This pair features a unique 37mm vs 27mm depth split while maintaining a uniform 32mm width. This creates an asymmetrical tactile experience, engaging different muscles in the hand and providing a more complex sensory track.
• The "Flat-Sided" Advantage: Because one wall is naturally flattened, these shells sit flush against the skin. They are exceptionally comfortable for long handling sessions and provide unique leverage for high-precision rotation.
• Signature "Chrysanthemum" Base: Retains the wide, stable base characteristic of the Sizuolou variety. Despite the mutation, the structural foundation remains dignified and balanced.
• Superior Bone Quality: Selected for high-density material. These walnuts produce a resonant "clinking" sound and are primed for a high-gloss, translucent mahogany transformation.
