[About the Imperial Seal Four-Rib Variety]

The Imperial Seal (Yu Xi) variety is named after the flat, expansive pedestal base and grounded stance resembling an emperor's ceremonial jade seal, traditionally symbolizing supreme authority, steady groundedness, and unwavering peace. The "Four-Rib" (Si Leng) designation indicates a rare natural growth mutation where the fruit forms four equidistant, cross-radiating primary edge rails instead of two, producing a multi-dimensional square seal profile. The "belly-dominant" trait means the lateral equator expands beyond the primary edge rails, creating a substantial rolling mass that rotates effortlessly across the palm without catching. Hallmark traits include an agile 39mm primary edge, an expansive 42mm belly fullness (+3mm belly dominance), four rounded lateral rails, an upright convergent low-profile blunt crown, and an expansive flat pedestal base with a deeply recessed navel that sits securely upright without tilt. The shell topography displays fluid vertical water-flow furrows crisscrossed by dense cellular honeycomb cavities and raised muscular veins, providing deep, invigorating acupressure stimulation across all palm contact points. Grown from prime mature wild orchards, its dense organic wood grain and rich natural oils allow it to age gracefully, transforming under regular play into a glowing, translucent mahogany-ruby heirloom finish.

[Characteristics of YX-E-034431]

• 39.0mm x 42.0mm Belly-Dominant Four-Rib Dun Proportions: Defying conventional dimensions, this set pairs an agile 39mm primary edge width with an expansive 42mm lateral belly girth (+3mm belly dominance), delivering high turning tension, multi-directional tactile engagement, and zero hand fatigue during extended play.

• Masterful Morphological Pairing: Both independent fruits exhibit balanced symmetry across their central cross-radiating blunt crowns, four sloping shoulders, multi-sided belly fullness, and deeply recessed foundational footprints.

• Deeply Channeled Honeycomb Topography: The surface features high-definition vertical water-flow valleys and crisp honeycomb cavities that provide an invigorating, full-contact tactile massage.

• Resilient Mountain Timber Density: Harvested from prime mature mountain orchards, the extra-thick shell walls carry a heavy, sink-in-hand weight and produce a clear, resonant ring upon manual rotation.

[Basic Care & Aging Info]

This collectible variety is grown strictly for hand-play (pan) and is completely distinct from common edible fruit variants. Through regular handling with clean, bare hands or white cotton gloves during early stages, the high-density wood grain steadily absorbs natural skin oils.

Artisan Coloration Tip: To keep the valleys and base cavities immaculate, brush the deep crevices thoroughly with a standard bristle brush after each handling session. Storing them back inside an airtight sealed bag when not actively playing will significantly accelerate the oxidation process, helping them develop a deep, glossy, translucent red-brown patina over time.
