[About the "Xinglong Dice Half-Wall" Variety]

This specimen represents a fascinating natural departure from the standard dice-shaped walnuts of the Xinglong region.

• The "Dice" Foundation: Known for their tall, boxy architecture and deep, pitted textures that resemble hand-carved gaming dice. Xinglong walnuts are famous for their extreme density and resonant sound.
• The "Half-Wall" Mutation: During growth, one wall developed significantly flatter than the other, resulting in a distinct "D-shape" profile.
• Ergonomic Leverage: Elite collectors prize Ban Bi mutations because the flat side rests flawlessly against the palm or fingers. This creates a specialized sliding and pressing mechanic that offers superior control and comfort compared to standard round or square varieties.

[Characteristics of XLBB-1201E]

• The "Half-Moon" Profile: Measuring 29.0mm in width and 38.0mm in depth, this pair is defined by its flat-sided silhouette. This allows the shells to sit flush against the skin, making them exceptionally comfortable for long, mindful manipulation sessions.
• Rugged Dice Texture: Despite the mutation, the surface retains the signature deep, rugged rippling and pitted folds of the Xinglong variety. It provides an intensive hand massage that targets acupressure points effectively.
• Ultimate Pocket Comfort: The flat-sided mutation naturally reduces the overall width and bulk of the walnut. This makes the pair spectacularly slim and an ideal choice for Everyday Carry (EDC).
• Resonant Bone Quality: Selected for high material density. These walnuts produce a clear, crisp porcelain ring and are primed to develop a rich, dark mahogany patina with a high-gloss finish.
