[About the Nanjiangshi Variety]

The Nanjiangshi variety is a historic and highly respected lineage within the classic Lion Head family, 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. 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-907]

• Flawless 1:1 Round Symmetry: Measuring an identical 42.0mm in width and 42.0mm in depth. Reaching a full 42mm provides a substantial, authoritative presence in the palm. This precise 1:1 geometric ratio yields a beautifully plump, spherical belly profile, allowing the two shells to roll past each other with smooth, fluid, and effortless motion during daily manipulation.
• 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. 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.
