[About the Nanjiangshi Lineage]

The Nanjiangshi variety is historically crowned as the "King of Density" within classic scholar walnut culture. It is instantly recognized by its signature structural geometry: a sweeping, wide-edged layout that mimics a traditional Chinese silver ingot (Yuan Bao), flanked by broad dropped shoulders, a short vertical axis, and a deeply recessed concave navel base. Revered for possessing the thickest internal shell walls and highest mass density of any lineage, it delivers an active, heavy sensory feel and requires a dedicated handling journey to unlock its legendary, bone-translucent dark mahogany patina.

[Product Characteristics of NJS-1005]

• The Robust 44mm Low-Profile Ingot Geometry: Measuring a substantial 44.0mm across the wide primary edges paired with a full 40.0mm belly depth. This intentional 4mm low-profile differential yields an exceptionally grounded, stout silhouette. The broad horizontal edges provide excellent rolling leverage across the hand, while the condensed 40mm vertical depth ensures the walnuts remain incredibly nimble across your fingertips for rapid, elegant twirling.
• Intricate Honeycomb Topography: The shell is enveloped in an absolute pristine network of natural "honeycomb" textures (Feng Wo Wen), characterized by thousands of deep, interlocking micro-pits and dense vertical ridges. This ultra-detailed texture completely avoids sharp or fragile points, providing unmatched high-friction traction against the skin while delivering an invigorating, deep-tissue palm massage.
• Deeply Recessed Concave Base Stance: Each piece features a wide, flared bottom layout with a distinctly deep, concave central navel. This architectural base allows each piece to stand stable on flat surfaces, while the straight vertical alignment along the main seams ensures an exceptionally balanced distribution of its heavy unit mass.
• Resonant Iron-Bone Acoustics: Grown to full wild maturity with extra-thick internal chamber walls, this pair carries immense physical weight relative to its footprint. When rotated past one another, the dense bone-like material produces a sharp, high-pitched metallic ring rather than a muffled wooden clack.

[Maintenance & Aging Advice]

Because the "Nanjiangshi" lineage features an exceptionally high shell density and an intricate matrix of honeycomb valleys, it is highly recommended to keep this pair in a sealed bag when resting between handling sessions for the first month. This practice traps natural skin oils effectively to guide a uniform, blotch-free oxidation process across both the microscopic peaks and deep basal valleys. Handling them directly with bare hands—completely skipping the use of gloves—is the definitive method to naturally guide them toward a deep, high-gloss translucent dark-red patina.
