[About the "Nanjiangstone Concave Base" Variety]

Nanjiangstone, widely known as "Nan Jiang Shi," is universally recognized as the absolute king of density and stone-like weight within the premium Lion Head (Shi Zi Tou) lineage. This legendary variety originates from the rugged, mineral-rich mountain regions of northern China. The highly sought-after "Concave Base" (Ao Di) sub-strain is defined by a deeply recessed, inward-curving bottom gate that sits beautifully flat and stable. In traditional folklore, this characteristic acts as a spiritual basin, symbolizing the gathering of positive energy and the anchoring of focus, clarity, and wealth protection.

Structurally, Nanjiangstone is renowned for its iconic high-dome cross, ultra-thick outer rind, and a uniquely knurled, cross-linked texture. Free of fragile points, it provides an authoritative, deep-tissue palm massage that channels intense reflexology feedback through the hands with unmatched tactile resilience.

[Characteristics of NJS-1010]

• Commanding 43mm x 41mm Proportions: Measuring a robust 43.0mm in width and 41.0mm in deep belly thickness, this pair stands out as a highly coveted, master-grade set. The near-spherical geometric architecture creates a profoundly full, substance-rich feel in the user's hand. This exquisite dimensional harmony guarantees that the two heavy shells bypass one another with absolute fluid precision, allowing for smooth, lifelong rotation sessions.
• Densely Knurled Cross-Linked Rind: The outer topography displays a textbook showcase of exceptionally tight, interwoven textures and broad primary channels. These thick, rolling, wood-dense patterns serve as a supreme reflexology tool, consistently stimulating the primary circulation endpoints and stress-relief zones across the palm with every turn.
• Legendary Iron-Like Weight & Woody Chime: Grown to absolute physical maturity with remarkably thick wood walls, this pair carries an authoritative, stone-like heft that sets Nanjiangstone apart from all other varieties. When rotated, the ultra-hard shells strike each other to produce a sharp, high-resonance, crystalline chime, validating the impeccable fiber density and pristine structural health of the collection.

[Expert Aging & Patina Tip]

Because Nanjiangstone possesses an incredibly dense, non-porous rind structure, it requires immense patience and dedication to develop its full potential. To ensure that the natural organic oils from your hands settle uniformly into both the complex cross-linked ridges and the deep valleys, store this pair in a sealed container or velvet pouch during rest periods for the initial month. Hand-rolling directly with bare, completely clean hands—entirely bypassing gloves—is the ultimate traditional method to cultivate a translucent, glassy, and deeply reflective red-jade patina.
