[About the Pinggu Ingot Lineage]

The Pinggu Yuan Bao variety is a historic heritage lineage highly celebrated for its geometric grandeur and exceptional density. It earns its unique name from its classic silver-ingot profile (Yuan Bao): featuring broad dropped shoulders, a compressed horizontal axis, wide sweeping borders, and an expansive, deeply set concave navel base. Grown to full wild maturity, this old-lineage variety is highly prized for its thick internal chamber walls and its ability to develop a deep, high-gloss translucent crimson patina over long-term handling.

[Product Characteristics of PGYB-1001]

• The Commanding Giant 46mm Inverse Deep-Belly Silhouette: Measuring 41.0mm across the primary wide edges paired with a massive 46.0mm in belly depth. This intentional 5mm inverse differential yields an exceptionally plump, high-contrast vertical posture. The nimble 41mm width ensures the pair remains comfortable and effortless to navigate between your fingertips for rapid twirling, while the protruding 46mm belly actively occupies the core of the palm.
• Wild Honeycomb & Net-Like Topography: True to its premium pedigree, the shell is sculpted with a magnificent network of deep vertical folds, interconnected cross-fissures, and heavy craggy ridges that form a beautiful honeycomb lattice texture. This rich pattern completely avoids sharp or fragile nodes, providing excellent non-slip friction against the skin while delivering an invigorating, deep-tissue hand massage.
• Deeply Recessed Concave Base Stance: Each piece features a wide, flared bottom layout with a distinctly deep, concave central navel. This architectural base allows each piece to stand stable on flat surfaces, while the straight vertical alignment along the main seams ensures an exceptionally balanced distribution of its heavy unit mass during handling.
• Resonant Wood-Bone Acoustics: Sourced from fully ripened heritage groves, this pair carries significant physical mass relative to its footprint due to extra-thick internal chamber walls. When rotated 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 "Pinggu Ingot" lineage features a highly responsive, bone-dense shell structure with an intricate matrix of honeycomb 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 prominent ridges and deep basal recesses. 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.
