[About the Pinggu "Square Box" Variety]

Originating from the renowned Pinggu district—a historically significant region for premium Wenwan walnuts—the "Fang Kuai" (Square Box) is a highly distinctive and sought-after variety. Unlike traditional round or teardrop shapes, this variety naturally develops a striking, squarish silhouette with pronounced, flattened sides and a very deep belly. This unique geometry completely transforms the handling experience, providing distinct leverage points and an incredibly full, satisfying roll in the palm.

[Characteristics of PGFK-601]

• Dramatic "Square" Profile: Measuring 33.0mm in width and an exceptionally deep 40.0mm in depth, this pair showcases the dramatic "Fang Kuai" geometry perfectly. The depth heavily outweighs the width, creating a highly pronounced, box-like silhouette that sits incredibly full and heavy in the hand.
• Ergonomic Leverage: The distinct, flattened sides of the square shape allow the walnuts to lock uniquely into the contours of the fingers. This provides an incredibly stable, non-slip grip and an engaging mechanical feel during rotation.
• Classic Pinggu Texture: The surface displays the deep, continuous, and robust ridge patterns characteristic of premium Pinggu walnuts. This texture delivers deep-tissue acupressure stimulation and ensures long-lasting durability.
• Daily Use: This is a phenomenal choice for users who prefer an alternative to traditional round shapes. The intense 33x40mm proportions offer a highly unique, deeply massaging tactile experience that makes for a deeply rewarding daily patina journey.
