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.\u003c\/p\u003e\n\u003cp\u003e[Characteristics of NJS-1508C]\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e41.0mm 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.\u003c\/li\u003e\n\u003cli\u003eProportional 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.\u003c\/li\u003e\n\u003cli\u003eSymmetrical 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.\u003c\/li\u003e\n\u003cli\u003eHigh 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.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e[Basic Care \u0026amp; Aging Info]\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eArtisan 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.\u003c\/p\u003e\n\u003cp\u003e[Specifications]\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVariety: Triangular Concave Base Nanjiangshi Lineage (Sanjiao Aodi Nanjiangshi \/ NJS)\u003c\/li\u003e\n\u003cli\u003eStock ID: NJS-1508C\u003c\/li\u003e\n\u003cli\u003eDimensions: 41.0mm x 38.0mm\u003c\/li\u003e\n\u003cli\u003eBase Features: Distinct concave foundation base (Aodi) with sloping triangular shoulders and a cleanly centered low-profile apex.\u003c\/li\u003e\n\u003cli\u003eTexture: Interconnected hive-like wrinkles, dense vertical channels, and a well-distributed surface grid layout.\u003c\/li\u003e\n\u003cli\u003eBest For: Collectors looking for an agile, low-profile Nanjiangshi pair with outstanding S-tier symmetry, a unique triangular concave-base profile, fluid rotation, and a fast-aging timber composition.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ThePatinaProject","offers":[{"title":"Default Title","offer_id":50654300537071,"sku":null,"price":198.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/8741\/8095\/files\/triangular-concave-base-nanjiangshi-sanjiao-aodi-nanjiangshi-njs-1508c-low-profile-wenwan-walnuts-pair-410mm-x-380mm-njs-1508c-7208821.jpg?v=1788251714","url":"https:\/\/zenwalnut.com\/zh\/products\/rare-triangular-nanjiangshi-wenwan-walnuts-41mm-x-38mm-njs-1508c","provider":"ThePatinaProject","version":"1.0","type":"link"}
