• [About the Concave Base Rain Flower Stone Variety]

The Concave Base Rain Flower Stone (BDYHS) variety is a unique, highly prized strain in the traditional Wenwan walnut community. Named after its fine, pebble-like surface wrinkles that evoke the smooth, organic textures of Yuhua river stones, this strain incorporates a concave foundation structure—where the bottom navel tucks inward for exceptional stability—to naturally restrict excess vertical growth. Built upon dense wild mountain stock, its compact framework expands along the equator to shift mass horizontally. The result is an agile, low-profile template that offers low rotational resistance, smooth turning leverage, and superb tactile feedback during single-handed palm rotation.

[Characteristics of BDYHS-17A3C]

• 35.0mm x 33.0mm Compact Stance: Featuring an agile, compact footprint (35mm height / 33mm width), this set offers a light, ultra-nimble template designed for effortless turning leverage and comfortable daily hand-play.
• Proportional Shape Match: The two independent walnuts demonstrate fantastic morphological pairing (rated S), mirroring each other with broad base foundations, uniform outer side profiles, and closely coordinated shoulder curves.
• Fine Yuhuashi Texture Matrix: Displaying intricate, interconnected pebble-like wrinkles and dense vertical channels, the refined rind surface actively stimulates acupoints across the entire palm during play.
• High-Density Wild Timber Rinds: Hard-grown from wild orchard stock, the extra-thick rinds possess superior organic density, generating a clear, solid, porcelain-like acoustic chime during manual rotation.

[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. Storing them back inside an airtight sealed bag when not in use will significantly accelerate the oxidation process, helping them develop a deep, translucent, red-brown patina over time.
