[About the "Mopan" Variety] The Mopan variety is a highly unique and historically celebrated heritage lineage within the classic Wenwan walnut hobby. It is named after traditional stone millstones (Mopan) due to its distinctive low-slung, wide-eared profile that features dropped shoulders and a naturally squatted vertical template. Cultivated from old-growth mountain timber, it concentrates its organic wood mass heavily along a robust horizontal equator, leaving minimal empty internal cavity space. The flat base foundation combined with smooth rolling curves provides exceptional turning traction and great handling leverage, ensuring a fluid, continuous single-handed palm rotation.

[Characteristics of MP-01SY]

• 40mm Agile Millstone Template: Measuring a precise 1:1 ratio of 40.0mm in both width and height, this pair presents a highly nimble, compact profile designed for exceptionally comfortable daily hand-play.
• Proportional Shape Match: The two independent walnuts show fantastic morphological pairing, mirroring each other with broad base foundations, uniform outer side profiles, and closely coordinated drop-shoulder curves.
• Symmetrical Grid Alignment: From a top-down perspective, 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 ring 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, bare hands, the high-density wood grain steadily absorbs natural skin oils. Over time, this natural interaction will cause the initial ginger-caramel wood tones to gradually transform into a deep, glossy, translucent red-brown patina. Because the signature texture paths and deep craggy channels are exceptionally dense and pocketed, it is highly recommended to brush the crevices thoroughly with a standard bristle brush after each use to keep the valleys immaculate.
