[About the "Thick Ridge" Variety]

The Cu Jin, translating to "Thick Ridge" or "Thick Vein," is a highly robust and profoundly tactile Wenwan variety. It earns its name from the exceptionally bold, raised, and thick ridge patterns that heavily dominate the shell. This exaggerated, muscular texture provides an incredibly aggressive, high-friction grip. It is heavily favored by collectors who seek a deeply engaging, heavy-hitting acupressure massage and a rugged, commanding visual aesthetic.

[Characteristics of CJ-803]

• Massive 1:1 Balance: Measuring a commanding 42.0mm in width and exactly 42.0mm in depth. Achieving a flawless 1:1 footprint at this giant scale is exceptionally rare. This perfect symmetry gives the walnuts a remarkably stable presence in the hand, allowing for an effortlessly smooth roll despite their massive size.
• Aggressive "Thick Ridge" Texture: True to its name, the surface displays remarkably thick, bold, and prominent veins alongside deep, cavernous valleys. This rugged, high-friction texture acts as a natural lock against the fingers, delivering intense, targeted deep-tissue stimulation during rotation.
• Heavy-Hitting Leverage: The thick ridges not only provide deep texture but also act as distinct mechanical leverage points, allowing the heavy shells to interlock and deliver a highly satisfying, tactile crunch as they move past one another.
• Daily Use: The perfectly proportioned 42x42mm dimensions make this a true heavyweight everyday carry (EDC) pair. It is the perfect choice for collectors who desire a giant, deeply rugged piece that still offers the refined handling of a flawlessly symmetrical shell.
