[About the Triangle Hollow-Base Variety]

The "Triangle Pinggu Hollow-Base" is a horticultural marvel. It combines the rare Three-Valve (Triangle) growth mutation with a "Hollow Base" (Ao Di)—where the bottom navel is naturally recessed inward. In Chinese walnut culture, the "Hollow Base" is a sign of a superior "Squat" (Ai Zhuang) lineage. This combination offers a unique, pyramidal grip and a perfectly grounded feel for advanced Mindful Meditation.

[Characteristics of PG-S-003064]

  • Rare 3-Sided "Low-Profile" Silhouette: Measuring 40mm in length with a slightly shorter 38mm width, this pair offers a stable, grounded "Pyramid" shape. The three prominent ribs provide a specialized Hand Massage, reaching deep into the palm's neural pathways to anchor your focus.
  • Refined "Pinggu-Silk" Texture: Sourced from the famous Pinggu region, the texture is dense and fluid, resembling cascading mountain streams. This "Medium-Relief" surface is perfect for Stress Relief and long sessions of rhythmic rotation.
  • Elite S-Grade Bone Density: These walnuts possess a hard, "porcelain-like" shell characteristic of the Pinggu terroir. You can expect a clear, musical "tink" during use—a hallmark of mature natural density.
  • Symmetrical S-Grade Matching: Matching the recessed "Hollow Base" and the three-sided alignment of a 40mm pair is an extraordinary challenge. This set has been curated for near-perfect symmetry in ridge distribution across all three sides.
