[About the Pinggu Yuan Bao Variety]

The Yuan Bao variety earns its descriptive name from its specific architectural posture, which perfectly mimics the flared, sweeping lines of a traditional Chinese "Sycee" silver or gold ingot (Yuan Bao). Originating from the historic wild trees of the Pinggu region, this lineage is characterized by prominent, wing-like sweeping shoulders, a low-slung central crown, and a distinctly squatted horizontal mass. Structurally, it is celebrated for its heavy unit weight, exceptionally thick shell walls, and a broad base layout that sits flat and stable.

[Product Characteristics of PGYB-804]

• The Dramatic Deep-Belly Geometry: Measuring 38.0mm in width paired with an expansive 44.0mm in belly depth. This substantial 6mm inverted differential creates a profound "deep-belly" architecture. While the 38mm width keeps the pair remarkably nimble and comfortable across the fingers during rotation, the protruding 44mm depth actively fills out the center of the palm, providing the massive volume of a much larger collector's tier pair.

• Textbook Sycee Silhouette: This pair features a dead-flat base layout and broad, angular, sweeping shoulders that frame a classic low-set crown. The vertical centerline seams are straight and cleanly aligned, ensuring a smooth path as the two shells glide past each other in the hand.

• Interconnected Ripple Topography: The surface displays a beautifully sculpted network of thick, rounded vertical ridges and deep, winding natural valleys. This fluid texture avoids sharp, spikey points, offering robust natural traction against the skin while delivering a relaxing palm massage.

• Resonant Wood-Bone Acoustics: Grown to full wild maturity with extra-thick internal chamber walls, this pair carries substantial mass relative to its size. During rotation, they produce a distinct, clear, high-density ceramic clack rather than a hollow wooden sound.

[Maintenance & Aging Advice]

Because the "Pinggu" lineage features highly dense bone material and specialized deep recesses, 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 and ensures that the oxidation process develops uniformly across both the high ridges and deep crevices. Handling them directly with bare hands—completely skipping the use of gloves—is the established method to naturally develop a deep, uniform translucent red patina.
