[About the Nanjiangshi Variety]

The Nanjiangshi variety is a historic and highly respected lineage within the classic Lion Head family, globally recognized for its stone-like bone density and distinct structural traits. Its physical architecture is characterized by a flat, highly stable base that sits completely square on flat surfaces, broad dropped shoulders, and a prominent, sharp centerline seam forming a classic "cross" at the tip. Due to its exceptionally thick shell walls and tight internal chamber structures, it carries a heavy unit weight and is known for having a slower, deeply layered oxidation process.

[Product Characteristics of NJS-805]

• The Proportional Deep-Belly EDC Geometry: Measuring a versatile 40.0mm in width paired with a robust 37.0mm belly depth. This specific dimensional ratio yields a beautifully plump, full-bodied layout. While the 40mm horizontal profile ensures that the pair remains nimble and easy to clear between your fingers during rotation, the protruding 37mm depth actively fills out the center of the palm.
• Textbook Architectural Stance: This pair features a dead-flat, table-stable base layout and wide, squared shoulders. The vertical alignment remains perfectly centered across the sharp centerline seam, ensuring a highly balanced distribution of mass and a predictable rolling path.
• Brain-Coral Texture Matrix: The surface is formed by a tightly woven, highly detailed network of fluid ridges and deeply pocketed valleys, resembling the texture of brain coral. This intricate topography provides steady traction against the skin, delivering an active and thorough hand massage during rotation without any spikey sharpness.
• Resonant Stone Acoustics: Grown to full wild maturity with extra-thick internal shell walls, this pair carries significant physical weight relative to its footprint. When spun past one another, they produce a distinct, high-pitched, metallic ceramic ring rather than a hollow wooden sound.

[Maintenance & Aging Advice]

Because the "Nanjiangshi" variety features an exceptionally high shell density and an intricate surface network of valleys, it is 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 an even oxidation across the entire surface area. Handling them directly with bare hands—completely skipping the use of gloves—is the definitive method to naturally unlock a translucent crimson patina over time.
