[About the Zheng Mo Pan Lineage]

The Zheng Mo Pan variety is historically celebrated for possessing one of the most structurally stable and geometrically distinct profiles in the entire scholar walnut kingdom. It gets its descriptive name from the traditional stone millstones due to its signature flattened top apex, wide dropped shoulders, and a broad, exceptionally flat "W-shaped" base. Grown to full wild maturity, this old-lineage variety is highly prized for its dense, shock-resistant wood-bone walls and its ability to develop a deep, high-gloss translucent crimson patina over long-term handling.

[Product Characteristics of MP-1301C]

• The Robust 45mm Low-Profile Form: Measuring a substantial 45.0mm across the primary wide edge paired with a full 43.0mm belly depth. This tight 2mm low-profile differential yields an exceptionally grounded, stout silhouette. The 45mm horizontal footprint offers excellent leverage in the hand, while the condensed vertical axis allows the pair to glide past one another effortlessly without colliding or catching.
• Iconic Flat Base & "W" Architecture: Built with near-flawless structural symmetry, each piece features a broad, expansive base that allows them to stand perfectly upright on any flat surface. The bottom navel area recesses into a beautifully defined, clean "W" curve, distributing the unit mass evenly around the lower perimeter for an incredibly smooth, predictable path during rotation.
• Flowing Ribbon Topography: The surface pattern is sculpted with a classic network of broad, shallow vertical folds and smooth, rounded natural channels. This texture completely avoids sharp spikes or prickly nodes, maximizing non-slip traction against the skin while delivering a relaxing, therapeutic palm massage.
• High-Density Wood-Bone Acoustics: Sourced from fully ripened wild heritage groves, this pair carries substantial physical weight relative to its size. The extra-thick internal chamber walls produce a sharp, high-pitched metallic ceramic click during handling, rather than a muffled or hollow wooden clack.

[Maintenance & Aging Advice]

Because the "Zheng Mo Pan" lineage features a highly responsive, bone-dense shell structure, it is recommended to keep this pair in a sealed bag when resting between handling sessions for the first month. This practice safely traps natural skin oils to guide a uniform, blotch-free oxidation process across the entire expanded surface area. Handling them directly with bare hands—completely avoiding the use of gloves—is the definitive method to naturally unlock a deep, mirror-like translucent jewel-red finish over time.
