[About the Da Ku Shi Variety]

The Da Ku Shi variety earns its descriptive name—meaning "Great Weathered Rock" or "Aged Dry Stone"—from its exceptionally rugged and dramatic shell topography. It is highly celebrated for possessing a deep, deeply layered matrix of continuous net-like wrinkles that mimic the raw, organic aesthetics of wind-eroded mountain crags and ancient petrified wood. Characterized by an upright vertical posture, high dropped shoulders, and a broad, table-stable base layout, this variety is highly regarded by advanced practitioners for its extreme wood-bone wall thickness and high-friction rolling mechanics.

[Product Characteristics of DKS-1301C]

• Flawless Substantive Near-1:1 Profile: Measuring 43.0mm in width paired with a full 42.0mm belly depth. This minimal 1mm dimensional differential yields an exceptionally grounded, stout silhouette. The 43mm footprint offers excellent horizontal leverage across the fingers, while the protruding 42mm depth actively fills out the center of the palm during rotation.
• Textbook Rugged Symmetrical Stance: Built with exceptional organic alignment, each piece features a broad, dead-flat base layout that allows them to stand perfectly upright on flat surfaces. The vertical centerline seams run completely straight and neatly centered, ensuring a highly predictable path and a perfectly balanced distribution of unit mass.
• Deep Multi-Layered Rock Topography: True to its premium pedigree, the surface is sculpted with a magnificent network of deep vertical valleys, interconnected cross-fissures, and heavy craggy ridges. This signature texture completely avoids sharp, fragile points, providing unrivaled non-slip traction against the skin while delivering an invigorating, deep-tissue palm massage.
• Resonant Wood-Bone Acoustics: Sourced from fully ripened wild heritage groves, this pair carries significant physical weight relative to its size due to extra-thick internal chamber walls. When rotated past one another, the mature bone-dense material produces a sharp, high-density metallic ceramic click rather than a muffled wooden clack.

[Maintenance & Aging Advice]

Because the "Da Ku Shi" lineage features an exceptionally rugged topography with deep natural fissures, it is 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 high ridges and deep valleys. Handling them directly with bare hands—completely avoiding the use of gloves—is the definitive method to naturally guide them toward a deep, high-gloss translucent crimson patina over time.
