[The Story of the Ye Niu Variety]

The Ye Niu lineage, translated as the "Wild Bison," is highly celebrated within traditional wood-bone collecting culture for possessing one of the most powerful topographies in the hobby. It earns its descriptive name from its muscular, deeply cratered shell structure: featuring dropped shoulders, extra-thick outer walls, and heavily sculpted vertical ridges that form rugged, shadowed cavities reminiscent of wild terrains.

In traditional culture, these deep, natural formations symbolize rugged strength, resilience, and an unyielding spirit. Sourced from classic wild northern groves, this variety is highly prized for its massive physical mass and extra-thick internal chamber walls. It carries an exceptional hand-weight relative to its footprint and responds beautifully to bare-hand handling, slowly turning from a warm golden-tan into a deep patina over a dedicated handling journey.

[Product Characteristics of YN-1107]

• Commanding 42mm Low-Slung Stance: Measuring a robust 42.0mm across the wide primary borders paired with a full 40.0mm vertical depth across the bellies. This close 2mm layout gives the pair a remarkably grounded horizontal expansion. The 42mm footprint stretches comfortably across the hand to provide superb mechanical leverage, while the flat 40mm belly depth allows the shells to slide seamlessly past one another during circular rotation.
• Deeply Cratered Topography: True to its lineage pedigree, the exterior shell is sculpted with a network of thick vertical bone folds, interconnected cross-fissures, and deep, cavernous pockets. This dramatic, high-relief texture completely avoids sharp spikes or fragile nodes, providing superior non-slip friction against the skin while delivering an invigorating micro-massage to hand pressure points.
• Textbook Flat Basal Stance & Open Seams: Each piece features a beautifully expansive, flat bottom layout with a clean, neatly centered navel that allows them to stand completely upright on flat surfaces. The main vertical centerline seams run exceptionally straight from the top apex down to the base, ensuring great tracking stability and a perfectly balanced distribution of its heavy unit mass during fast handling.
• Resonant Wood-Bone Acoustics: Sourced from fully ripened heritage lines, this pair carries significant physical weight relative to its footprint due to extra-thick internal wood-bone walls. When rotated or twisted past one another, the mature material produces a sharp, clean wooden click.

[Maintenance Advice]

Because the "Ye Niu" lineage features a highly responsive shell structure with an intricate network of deep flowing valleys and cavities, 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 to guide a uniform, blotch-free oxidation process across both the muscular peaks and deep recesses. Handling them directly with bare hands—completely skipping the use of gloves—is the most effective way to naturally develop a deep, uniform patina over time.
