[About the "Sanjiao Aodi Nanjiangshi" Variety] The Nanjiang Stone variety is globally celebrated as one of the most durable, dense, and slow-aging families within the classic Wenwan walnut hobby. The "Sanjiao Aodi" variant represents an elite double natural mutation. It develops three distinct, symmetrical side faces instead of a traditional two-sided ridge line, creating a unique pyramidal architecture. Furthermore, the base features an "Aodi" (concave foundation gate) mutation, where the core naturally recesses upward. This structural combination packs high-density wild timber tightly across a compressed vertical axis, providing an exceptionally substantial weight, low rolling resistance, and crisp tactile feedback across the palm for fluid hand rotation and daily sensory meditation.

[Characteristics of NJS-1514C]

• 41mm Agile Low-Profile Frame: Measuring a stout 41.0mm in width and a squatted 39.0mm in height, this pair carries an elite, low-profile stance that rests securely in the palm for comfortable handling.
• Proportional Shape Match: The two independent walnuts show master-tier morphological pairing, mirroring each other with broad triangular foundations, matching side profiles, and closely coordinated high shoulder curves.
• Symmetrical Grid Alignment: When viewed from a top-down perspective, the set exhibits highly balanced three-way ridge paths, uniform outer shell thickness, and perfectly centered top apex points running across both rinds.
• High Bone Density Wild Timber: Hard-grown from wild old-growth mountain orchards, the extra-thick rinds possess exceptional organic density, generating a clear, solid, porcelain-like acoustic ring during manual play.

[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, the high-density wood grain steadily absorbs natural skin oils. Over time, this natural interaction will cause the initial ginger-caramel coloration to transform into a deep, glossy, translucent red-brown patina. Because the signature texture paths are exceptionally deep, sharp, and tightly woven, it is highly recommended to brush the crevices thoroughly with a standard bristle brush after each use to keep the valleys immaculate.
