[About the Millstone Variety]

The Millstone (Mopan) variety is one of the most famous, highly prized classic strains in the traditional Wenwan walnut community. Named after the traditional stone mill for its distinctly flattened top apex, wide horizontal waist, and low vertical stature, this strain naturally restricts excess vertical growth while fanning out along its equator. Built upon wild mountain timber heritage, its extra-thick rinds shift mass horizontally across its equator 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 feedback during single-handed palm rotation.

[Characteristics of MB-17F4]

• 40.0mm x 37.0mm Low-Profile Template: Presenting an agile, well-proportioned stance (40mm width / 37mm height), this pair offers a compact, hand-filling footprint designed for smooth turning leverage and comfortable daily hand-play.
• Proportional Shape Match: The two independent walnuts demonstrate outstanding morphological pairing (rated S), mirroring each other with broad base foundations, uniform outer side profiles, and closely coordinated drop-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 Wild Timber: Hard-grown from wild 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.
