[The Story of the Four-Ribbed Jiulongjin Lineage]

The Jiulongjin (Nine Dragons Sinew) family is universally recognized in traditional wood-bone collecting culture as one of the most visually aggressive and intensely sculpted lines in existence. It earns its legendary name from its raw shell morphology: featuring heavy, twisting vertical ridges that resemble muscular dragons tracing along the body.

A true Four-Ribbed (Sileng) specimen represents an exceedingly rare genetic phenomenon where the walnut naturally forms four distinct, fully developed primary edge seams that divide the shell into a perfect 90-degree cross profile.

In traditional heritage folklore, a four-ribbed layout serves as an ancient symbol of complete stability, quad-directional protection, immense prestige, and an unshakable mind. Sourced from high-altitude ranges, its bone-dense wood fiber responds beautifully to bare-hand manipulation, shifting naturally from a warm golden-tan into a deep, highly translucent ruby-red patina over time.

[Product Characteristics of JLJ4N-1001E]

• Monumental 43x52mm Inverse Posture: Measuring 43.0mm across the primary ribs paired with a massive 52.0mm depth across the bellies. This striking 9mm inverse ratio gives the pair immense tactile volume relative to its width. While the 43mm footprint sits comfortably across your fingers, the 52mm protruding deep bellies actively dominate the core of the palm for an unprecedented, heavy rolling sensation.
• Flawless Cross-Axial Symmetry: True to its rare mutation, the four primary vertical ribs run straight down the body from the pointed apex to the base. This splits the body into four perfectly proportioned, deeply cratered quarter-panels, creating a striking cross-star geometry when viewed directly from above or below.
• Intensely Sculpted Dragon-Ridge Topography: The exterior shell is sculpted with a masterfully balanced network of deep honeycomb pockets, jagged natural fissures, and massive, thick vertical lines. This high-relief, continuous texture completely avoids sharp spikes or fragile nodes, providing excellent non-slip skin traction while delivering an invigorating micro-massage to hand pressure points.
• Iron-Bone Acoustic Resonance: Sourced from fully ripened wild orchards with extra-thick internal wood-bone walls, this pair carries immense physical weight. When rotated or spun past one another, the mature bone-dense material produces a sharp, clean high-pitched ceramic chime rather than a muffled wooden clack.

[Maintenance Advice]

Because the "Nine Dragons Sinew" four-ribbed mutation features a highly responsive, bone-dense shell structure with an intricate network of deep surface 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 lipids to guide a uniform, blotch-free oxidation process across both the prominent ribs and deep interior recesses. Handling them directly with bare hands—completely skipping the use of gloves—is the definitive method to naturally develop a deep, high-gloss patina over time.
