[About the San Jiao Wa Three-Rib Variety]

The San Jiao Wa lineage, translated as the "Horned Frog," combined with the highly coveted Three-Rib (San Leng) structural mutation, represents one of the most mechanically fascinating and visually dramatic topographies in the classic wood-bone hobby. It earns its descriptive name from its multi-axis organic architecture: featuring three naturally formed, evenly spaced vertical bone ridges that outline a distinct triangular stance, paired with heavily raised, knobby skin textures that beautifully mirror the rugged exterior of a wild desert horned frog. This rare form offers immense multi-directional friction and delivers a highly stimulating tactile roll across the palm's pressure points.

[Product Characteristics of W-1007]

• The Dramatic 38mm Inverse Deep-Belly Posture: Measuring 36.0mm across the primary wide edges paired with a full 38.0mm in belly depth. This intentional 2mm inverse profile yields an exceptionally plump vertical posture. The nimble 36mm width ensures the pair remains comfortable and effortless to navigate between your fingertips for rapid twirling, while the protruding 38mm deep belly actively occupies the core of the palm.
• Three-Axis Hexagonal Bone Wave Symmetry: True to its elite pedigree, the shell showcases a masterfully balanced three-ribbed structure, yielding three independent natural flat planes. This structural geometry ensures an exceptionally balanced distribution of its heavy unit mass, allowing the walnuts to roll along a highly predictable path with immense stability.
• Craggy, High-Contrast Frog-Skin Topography: The surface fields a magnificent network of thick, heavily carved vertical bone folds, interlocking micro-fissures, and heavy craggy ridges. This aggressive texture completely avoids sharp spikes or fragile nodes, providing excellent non-slip traction against the skin while delivering an invigorating, deep-tissue hand massage.
• Textbook Flat Basal Stance & Open Seams: Each piece features a broad, dead-flat base layout with a centered navel that allows it to stand completely upright on flat surfaces. The three major vertical centerline seams run clean and neatly centered from the top apex down to the base, ensuring great leverage during intensive handling.
• High-Pitch Iron-Bone Acoustics: Sourced from fully ripened heritage groves, this pair carries significant physical weight relative to its footprint due to extra-thick internal chamber walls. When rotated or spun past one another, the mature bone-dense material produces a sharp, high-pitched metallic ring rather than a muffled wooden clack.

[Maintenance & Aging Advice]

Because the "San Leng San Jiao Wa" lineage features an exceptionally high shell density and an intricate matrix of rugged 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 safely traps natural skin oils to guide a uniform, blotch-free oxidation process across both the muscular prominent peaks and deep 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 crimson patina over time.
