[About the "Sanjiao Nanjiangshi" Variety] The Nanjiang Stone variety is highly celebrated as one of the most durable, dense, and slow-aging families within the classic Wenwan walnut hobby. The "Sanjiao" (Triangle) variant is a highly coveted natural mutation that develops three distinct, symmetrical side faces instead of the traditional two-sided ridge structure. This pyramidal architecture concentrates its old-growth wood mass uniformly, minimizing internal empty chamber space to give the pair an exceptionally substantial weight and stone-like hardness in the hand. The rugged surface features sharp, cord-like vertical lines and deep hive pockets, providing aggressive tactile feedback and excellent traction across the palm for deliberate bare-hand rotation.

[Characteristics of NJS-1512C]

• 38mm Balanced Symmetrical Posture: Measuring an exact 1:1 ratio of 38.0mm in width and height, this pair presents a highly nimble, compact footprint that fits comfortably in the hand for crisp pocket play.
• Proportional Shape Match: The two independent walnuts show master-tier morphological pairing, mirroring each other with broad triangular foundations, uniform side angles, and closely coordinated high shoulders.
• Symmetrical Grid Alignment: When viewed from a top-down perspective, the set exhibits highly balanced three-way ridge tracks, highly consistent outer shell thickness, and cleanly centered apex points across both pieces.
• High Bone Density Wild Timber: Hard-grown from wild mountain orchards, the massive rinds possess exceptional organic density, generating a clear, solid, porcelain-like acoustic ring during hand rotation.

[Basic Care & Aging Info] This collectible variety is grown strictly for hand-play (pan) and is completely distinct from common edible food 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 steadily transform into a deep, glossy, translucent red-brown patina. Because the signature texture paths are exceptionally deep 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.
