[About the Tuantuan Variety]

The Tuantuan variety earns its descriptive name from the Chinese term "Tuan Tuan," which signifies perfect roundness, completeness, and unity. Positioned within the classic low-profile (Ai Zhuang) scholar walnut family, it is highly celebrated for its distinctive spherical, ball-like architecture. Characterized by broad wrapped shoulders, a short vertical axis, and a completely flat, table-stable base, this variety is highly regarded for its dense shell material and an incredibly smooth rolling path.

[Product Characteristics of TT-1001]

• Flawless Spherical Near-1:1 Profile: Measuring 38.0mm in primary horizontal width paired with a full 37.0mm belly depth. This minimal 1mm dimensional differential yields a beautifully uniform, ball-shaped layout. The compact 38mm footprint makes the pair highly nimble and effortless to clear across your fingers for rapid, elegant twirling, while its plump sides sit comfortably in the hand.
• Textbook Low-Profile Stance: True to its premium lineage, this pair features a very compact vertical axis with dropped, wrapped shoulders and a dead-flat base layout. The vertical centerline seams run completely straight and neatly centered, ensuring an exceptionally balanced distribution of unit mass and a predictable rolling path.
• Fluid Rippled Topography: The surface displays a beautifully distributed matrix of thick, rounded wrinkles and clear, smooth natural channels. This topography completely avoids any sharp or spikey points, providing excellent non-slip traction against the skin while delivering a relaxing micro-massage during daily handling.
• Resonant Wood-Bone Acoustics: Grown to full wild maturity with highly robust, extra-thick internal chamber walls, this pair carries significant physical weight relative to its size. When rotated past one another, the mature wood-bone material produces a sharp, high-density metallic ceramic click rather than a muffled wooden clack.

[Maintenance & Aging Advice]

Because the "Tuantuan" lineage features an exceptionally high shell density and an intricate matrix of surface recesses, it is recommended to keep this pair in a sealed bag when resting between handling sessions for the first month. This practice traps natural skin oils effectively to guide a uniform, blotch-free oxidation process across the entire expanded surface area. Handling them directly with bare hands—completely avoiding the use of gloves—is the definitive method to naturally guide them toward a deep, translucent crimson patina over time.
