[The Lore: The Modern Classic "137"]

In the Wenwan community, the "137" (Yi San Qi) is a modern legend. Named after the numerical designation tied to its original discovery, this variety has skyrocketed in popularity to become a top-tier favorite among serious collectors.

The 137 is universally celebrated for its incredibly plump, nearly perfectly spherical natural growth. It is defined by its thick, prominent edges, a wide belly, and a texture that is exceptionally elegant and smooth. Because the ridges are robust rather than sharp and biting, playing with a single 137 walnut provides an incredibly comfortable, seamless, and frictionless roll in the palm, making it the perfect pocket companion for hours of relaxing, prick-free play.

[Why the 137-301 is a Premium Pick]

• Flawless 1:1 "Perfect Sphere" Ratio: Measuring exactly 37.0mm in width and 37.0mm in height, this single walnut hits a highly coveted, perfectly spherical 1:1 proportion. At a nimble 37mm, this is the ultimate Everyday Carry (EDC) sweet spot. It is exceptionally pocket-friendly and rolls with a fast, fluid rhythm in the hand.
• Ultra-Comfortable Relief: The surface of 137-301 features the signature clean, well-defined, and evenly distributed network of ridges that the variety is famous for. This unadorned, classic texture provides a deeply soothing, medium-intensity massage that focuses purely on comfort.
• Thick Edges & Stable Base: True to the highest standards of the 137 variety, this piece features beautifully thick, pronounced side edges and a highly stable base, giving it a very substantial and satisfying feel despite its compact size.
• Premium Bone Density & Timber: Hand-selected for its dense, mature shell. This single walnut boasts excellent bone density and is primed to rapidly absorb natural oils, transforming into a breathtaking, highly translucent dark-red patina with dedicated daily brushing.
