[About the "Zheng Mopan" Variety]

The Zheng Mopan variety is one of the "Four Famous Walnuts," traditionally valued for its unique disk-like shape that resembles an ancient stone mill or grindstone.

• Grindstone Architecture: This variety is defined by an exceptionally flat base and a squashed lateral spread, offering a low center of gravity and unmatched stability in the palm.
• Structural Stability: Provides a heavy, powerful "in-hand" feel, making it the premier choice for collectors who prefer specimens that sit firmly against the skin during rotation.
• Dense, Rippling Texture: Known for its thick, "bready" ridges and deep organic pits that provide a high-leverage tactile experience.
• Intense Hand Massage: The rugged topography effectively targets deep pressure points in the palm to promote circulation and mental clarity.
• Exceptional Bone Quality: Hand-selected for superior mineral density. These walnuts produce a solid, deep resonant sound during manipulation—a hallmark of mature material primed for a world-class patina transformation.

[Characteristics of MP-1201C]

• Commanding 42mm Breadth: This large-format pair offers a powerful, hand-filling presence. The 42.0mm width provides incredible leverage for specialized "sliding" and "pressing" mechanics.

• Synchronized Ridge Flow: The structural lines sweep with surgical precision from the flat base to the centered crown, creating a harmonious architectural flow.
• Auspicious Silhouette: When stacked, the pair demonstrates perfect vertical alignment and consistent density.
• Investment-Grade Patina: Selected for its uniform natural maturity to ensure the pair transforms into a deep, translucent mahogany-red with high-gloss highlights.
