[About the Cao Da Long Variety]

The Cao Da Long variety is a historic, wild-derived lineage named after its discovery area and its signature dragon-scale-like topography. Structurally, it is characterized by an upright, blocky silhouette, broad imposing shoulders, a flat base, and prominent, heavy-set centerline seams. It is widely recognized among experienced enthusiasts for its exceptional bone shell thickness, high structural mass, and a deeply textured surface that provides an intense tactile feel.

[Product Characteristics of CDL-1102]

• The Nimble Deep-Belly EDC Profile: Measuring 35.0mm in width paired with a robust 36.0mm belly depth. This subtle 1mm inverse differential creates a remarkably plump, deep-bellied layout. It offers a compact, pocket-friendly 35mm footprint that is highly agile across the fingers, while the protruding 36mm depth actively fills out the center of the palm during rotation.
• Stable High-Posture Silhouette: This pair features a dead-flat base layout and straight, squared shoulders. The primary vertical seams are clean, prominent, and perfectly aligned, ensuring a balanced distribution of mass and a highly predictable rolling path.
• Bold, Muscular Ridge Matrix: The surface is heavily sculpted with a dense, interconnected network of broad, fluid vertical ridges and deep, winding natural valleys. This dragon-scale texture avoids sharp, spikey points, providing excellent natural traction against the skin while delivering an active, deep-tissue hand massage.
• Dense Wood-Bone Acoustics: Grown to full wild maturity with exceptionally robust internal chamber walls, this pair carries significant physical weight relative to its size. When rotated past one another, they produce a distinct, high-density porcelain ring rather than a hollow wooden clack.

[Maintenance & Aging Advice]

Because the "Cao Da Long" lineage features highly dense bone material and bold vertical recesses, 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, blotch-free oxidation process across the entire surface area. Handling them directly with bare hands—completely avoiding the use of gloves—is the recommended method to naturally unlock a deep, translucent crimson-agate patina.
