Cao Dalong Wenwan Walnut · 43mm · Sourcing Pick

Medium-tall profile walnut with upright high tip, thick sturdy rims and full plump belly, marked with distinctive vertical Sichuan grain and classic concave wine-cup base. It features ultra-fine crystal waxy cortex with rich natural oil, weighting solid in palm and oxidizing rapidly during rolling. After long-term polishing, it develops translucent pinkish oxblood red patina with glossy jelly jade luster. Well-matched intact pairs are scarce high-value collectibles favored by veteran wenwan collectors.
