The name translates directly to its defining feature: \"Da\" (Large) and \"Cu Jin\" (Thick Ridge or Vein). Unlike varieties with fine or chaotic textures, the Da Cu Jin is famous for its bold, meaty, and pronounced surface ridges. This heavy structural relief provides a high-friction grip and deep stimulation during hand exercises.\u003c\/p\u003e\n\u003chr data-path-to-node=\"10\"\u003e\n\u003ch3 data-path-to-node=\"11\"\u003e\u003cb data-path-to-node=\"11\" data-index-in-node=\"0\"\u003e[Characteristics of CJ-402]\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"12,0,0\"\u003e\n\u003cb data-path-to-node=\"12,0,0\" data-index-in-node=\"0\"\u003eUpright Profile:\u003c\/b\u003e Measuring 40.0mm in width and 41.0mm in height, this pair has a slightly taller, upright shape.
