[About the Butterfly Millstone Variety]

The Hudie Mo Pan variety is historically celebrated as one of the most structurally majestic lineages within classic scholar walnut culture. It earns its descriptive name from its distinctive, flared multi-axis geometry: the raw shell forms highly dropped, squared shoulders, a dramatically shortened vertical axis, and expansive side rims that sweeping outwards like a butterfly opening its wings (Hu Die Bian). This specific profile is highly favored by advanced collectors for its ability to provide a massively substantive, palm-filling volume while remaining completely effortless to twirl without catching.

[Product Characteristics of MP-1351C]

• The Commanding Giant 46mm Low-Profile Stance: Measuring 46.0mm across the primary wide borders paired with a compressed 40.0mm height profile. This deliberate horizontal expansion gives the pair an impressive low-slung stance. The wide 46mm footprint stretches across the fingers to provide excellent physical leverage, while the flat 40mm depth allows the shells to slide seamlessly over one another without catching during rapid rotation.
• 44 Grams of Solid Iron-Bone Mass: Grown to full wild maturity with extra-thick internal chamber walls, this pair carries an immense 44g physical weight relative to its compressed footprint. When rotated past one another, the mature bone-dense material produces a sharp, high-pitched metallic ceramic click rather than a dull wooden clack.
• Flowing, Non-Aggressive Ribbon Topography: True to its premium pedigree, the exterior showcases a masterfully balanced network of broad, fluid vertical folds and clear, open natural valleys. This organic texture completely avoids sharp spikes or fragile nodes, offering steady non-slip friction against the skin while delivering a relaxing, thorough hand massage.
• Thick Prominent Ingot Borders & Stable Base: Each piece features an incredibly thick, flared side border that wraps tightly down to a wide, flat bottom layout with a slightly recessed central navel. This architectural base allows each piece to stand perfectly stable on flat surfaces, ensuring an exceptionally balanced distribution of its heavy unit mass.

[Maintenance & Aging Advice]

Because the "Hudie Mo Pan" lineage features an exceptionally high shell density and an intricate matrix of valleys around its compressed base, it is highly recommended to keep this pair in a sealed bag when resting between handling sessions for the first month. This practice safely traps natural skin oils to guide a uniform, blotch-free oxidation process across both the prominent ridges and deep valleys. Handling them directly with bare hands—completely avoiding the use of gloves—is the definitive method to naturally guide them toward a deep, high-gloss translucent crimson patina over time.
