[About the Triangular Concave Base Nanjiangshi Variety]

The Triangular Concave Base Nanjiangshi (Sanjiao Aodi Nanjiangshi) variety is an extraordinary, highly coveted specialized strain in the traditional Wenwan walnut community. Renowned for its classic two-ridge structure formed into a sharp triangular outline combined with a deep, arched foundation base (Aodi), this strain pairs signature lateral base breadth with a tapered apex. Built upon heavy mountain timber heritage, its extra-thick rinds shift mass toward the foundation to maximize palm contact. The result is a heavy, perfectly balanced low-profile framework that lowers rolling resistance across the fingers for fluid continuity, smooth turning leverage, and superb tactile acupressure feedback during single-handed palm rotation.

[Characteristics of NJS-1508C]

• 41.0mm x 38.0mm Low-Profile Template: Presenting a well-proportioned mid-to-large stance (41mm height / 38mm width), this pair offers an agile, hand-filling footprint designed for effortless turning leverage and deeply satisfying daily hand-play.
• Proportional Shape Match: The two independent walnuts demonstrate outstanding morphological pairing (rated S), mirroring each other with deeply recessed concave bases, uniform outer side profiles, and closely coordinated triangular shoulder curves.
• Symmetrical Grid Alignment: From both top-down and profile perspectives, the set highlights highly consistent central main ridge tracks, uniform outer rind thickness, and beautifully aligned center pathways running across both shells.
• High Bone Density Mountain Timber: Hard-grown in classic mountain orchards, the extra-thick rinds possess exceptional organic density, generating a clear, solid, porcelain-like acoustic chime 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 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. 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.
