[About the "Imperial Seal" Tri-Edge Variety]

The Yu Xi, translating to the "Imperial Seal," is an authoritative Wenwan variety known for its broad, blocky structure and exceptionally flat base, mimicking the ancient stone stamps used by emperors.

However, what elevates this specific pair to absolute Collector Grade is the "Tri-Edge" (San Leng) natural mutation. Standard walnuts possess two structural seams. A Tri-Edge is an astronomically rare genetic anomaly where the shell develops three distinct seams. To find a single Tri-Edge is incredibly lucky; to find two that match flawlessly is a true rarity. Furthermore, this pair features the highly coveted "Y-Shape" alignment—meaning when viewed from the top, the three edges are perfectly spaced to form a symmetrical "Y". In Eastern culture, a Tri-Edge is the ultimate symbol of supreme rarity, offering a completely unique, three-point tactile grip that simply cannot be replicated by standard shells.

[Characteristics of YSSN-1202E]

• Flawless Y-Shaped Mutation: The three edges on each walnut are beautifully defined and symmetrically spaced, creating the perfect "Y" shape. This three-point geometry provides a remarkably satisfying, locked-in grip that stimulates the acupressure points of the hand entirely differently than a standard two-edged walnut.
• Compact Width, Plump Belly: Measuring a highly portable 38.0mm in width but a distinctly deeper 39.0mm in depth. This subtle differential ensures the depth noticeably exceeds the width, giving this mutated pair a wonderfully round, protruding belly. They sit perfectly in the palm, offering a substantial and space-filling roll despite their pocket-friendly scale.
• The "Seal" Posture: True to the Imperial Seal lineage, these Tri-Edges feature exceptionally flat, stable bases. When not in use, they sit perfectly upright on a desk like a pair of royal artifacts.
• Expert Aging Tip: Because the Tri-Edge mutation creates deep, three-way valleys, we highly recommend resting them in a sealed bag between handling sessions for the first two to three weeks. This expert technique safely utilizes natural hand oils to accelerate an even, brilliant oxidation across the unique three-point structure, yielding a vibrant red patina far more effectively than using gloves.
