The Singular Edge brings the Yi-Dao-Jin variety into a personal Wenwan collection. Its ridge-inspired name offers a theme for a hands-on collecting ritual. Keep the pair beside a favorite book or at your workspace, ready to pick up during a quiet pause.

Recorded heights of 31.2 and 29.7 mm are lower than the edge and belly measurements, giving this pair relatively low proportions. Edge measurements differ by 1.4 mm, belly widths by 0.9 mm, and heights by 1.5 mm. Individual weights of 15.1 and 17.6 g differ by 2.5 g. This is a measured weight difference, not a verified density difference or a guarantee of balanced rotation.

  • Product ID: w7570
  • Product Variety: Yi-Dao-Jin
  • Sphere A Dimensions (Edge / Belly / Height): 40.7 mm × 39.2 mm × 31.2 mm
  • Sphere A Weight: 15.1 g
  • Sphere B Dimensions (Edge / Belly / Height): 39.3 mm × 38.3 mm × 29.7 mm

  • Dynamic Pairing: 2.5 g weight variance; combined net weight 32.7 g.

The documented proportions and individual differences form part of the pair's collectible identity. One edge measurement exceeds 40 mm while the other does not; compare both sets of dimensions with your preferred handling size rather than relying on a single size label.

All dimensions and weights are hand-measured with precision tools; slight variations may occur.
