One-Rib Toad Head Wenwan Walnut · 39mm · Select Ritual

A rare premium variant of Toad Head, famous for its single continuous central rib (one 筋) running straight from top to bottom—called “One-Rib” or “Single Spine.” Features classic toad-shaped plump body, wide flat base, and bumpy toad-skin texture. High-density oily bone, heavy in hand, with fast even coloring to glossy amber-red patina. Extremely rare due to low natural yield; perfect for collectors seeking unique, eye-catching pieces.
