[About the "Mopan" Variety] The Mopan variety is an iconic, highly prized heritage lineage within the Wenwan walnut hobby. It is named after traditional stone millstones due to its naturally flat base, significantly compressed vertical axis, and distinctive low, dropped shoulders. This variety naturally concentrates its organic wood mass heavily along the lower equator line, minimizing empty chamber space inside the shell. This unique geometry drastically reduces rolling resistance across the fingers, offering substantial physical presence, superb handling leverage, and an incredibly smooth continuity for rhythmic palm rotation and daily sensory meditation.

[Characteristics of MP-1002]

• 42mm Versatile Squat Frame: Measuring a perfectly proportioned 42.0mm in width and a compressed 41.0mm in height, this pair presents a highly adaptable template that rests comfortably and securely in the hand.
• Proportional Shape Match: The two independent walnuts show fantastic morphological pairing, mirroring each other with broad base foundations, uniform outer contours, and a well-balanced horizontal center of gravity.
• Symmetrical Grid Alignment: The top-down and profile perspectives highlight highly consistent ridge paths, uniform outer shell thickness, and perfectly centered top apex points running across both rinds.
• High Bone Density Timber: Hard-grown from wild old-growth mountain trees, the thick rinds possess exceptional organic density, generating a clear, solid acoustic ring 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, the high-density wood grain steadily absorbs natural skin oils. Over time, this natural interaction will cause the initial golden-caramel coloration to gradually darken into a deep, glossy, red-brown patina. To keep the fine craggy lines pristine and prevent dust accumulation in the deeper valleys, it is recommended to brush the crevices thoroughly with a standard bristle brush after each handling session.
