[About the "Wild Bull" Quad-Ridge Variety]

The Wild Bull variety is revered for its aggressive, unyielding character and its exceptionally hard shell. The Four-Ridge mutation is a biological rarity that occurs in less than one in ten thousand wild walnuts.

• The "Cross" Apex: Unlike standard walnuts with two ridges, this mutation features four primary ridges that intersect at the top to form a perfect, symmetrical cross. Achieving this structural precision in a large 42mm frame is a significant collector's milestone.
• Aggressive Tactile Geometry: The four-ridge structure creates four distinct "valleys" for the fingers. Combined with the "Wild Bull" texture, it provides a multifaceted tactile track that offers unparalleled grip and an intensive hand massage.
• Elite Material Density: Wild Bull walnuts are known for their heavy "bone" quality. They produce a sharp, metallic "clinking" sound that signifies superior material maturity and high oil content.

[Characteristics of YNFN-1301E]

• Commanding 42mm Presence: This is a substantial, large-format pair. The 42.0mm width provides incredible leverage in the palm, making it an ideal choice for those who prefer heavy, powerful specimens.
• Impeccable Structural Symmetry: The cross-shaped apex on both walnuts is centered and crisp. This ensures a balanced, uniform feel in the hand, allowing for smooth, rhythmic manipulation despite the rugged texture.
• Deep, Rugged Texture: The surface is rich with the deep, winding folds and pitted topography characteristic of the Wild Bull variety. It effectively targets the palm's pressure points to promote circulation and mental focus.
• Premium Patina Potential: Hand-selected for uniform maturity. As these walnuts absorb natural oils, they will transform into a deep, translucent mahogany-red that highlights the complex geometry of the four-sided frame.
