[About the Triangular Concave Base Nanjiang Stone Variety]

The Triangular Concave Base Nanjiang Stone variety is an extraordinary, highly prized strain in the traditional Wenwan walnut community. Known for its extreme density, heavy weight, and deep, intricate rind textures, Nanjiang Stone represents the pinnacle of long-term patina development. By incorporating a "Triangular Aodi" (Concave Base) structure—where the bottom navel tucks inward into a distinct triangular/rhombic form for exceptional stability—this variety provides a solid foundation with impressive visual presence. Built upon wild mountain timber stock, this compressed framework shifts its mass evenly to maximize palm contact. The result is a heavy, perfectly balanced template that offers smooth rotational flow, superb tactile feedback, and incredible durability during single-handed palm rotation.

[Characteristics of NJS-1507C]

41.0mm x 41.0mm Full-Volume Template: Presenting a remarkably full, well-proportioned stance with broad 41mm edges, this pair offers a hand-filling, substantial footprint designed for smooth turning leverage and deeply satisfying daily hand-play.

Proportional Shape Match (S+ Grade): The two independent walnuts show exceptional morphological pairing (rated S+), mirroring each other with matching broad shoulder curves, uniform outer side profiles, and precise structural balance.

Deep Intricate Texture Matrix: Featuring classic deep "cabbage-like" wrinkles and dense, wild cratered channels, the set displays a rich surface grid that stimulates acupoints across the entire palm during rotation.

High-Density Wild Timber Rinds: Hard-grown from dense wild stock, the extra-thick rinds possess exceptional organic density and weight, 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 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 immaculate, brush the deep crevices thoroughly with a standard bristle brush after each handling session. Because Nanjiang Stone timber is exceptionally dense, it requires patient playing; storing them back inside an airtight sealed bag when not in use will significantly accelerate the oxidation process, helping them develop a deep, glossy, glass-like translucent red-brown patina over time.
