It earns its descriptive name from its distinctive organic geometry, which naturally mimics the tapered, anatomical shape of a heart. Characterized by an upright vertical stance, a distinctly pointed apex (tip), tightly sloped shoulders, and a substantial, deep belly, this variety is highly regarded for its dense shell material and exceptional rolling mechanics.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003e[Product Characteristics of BJJX-1001]\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"13,0,0\"\u003e\n\u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"0\"\u003eClassic Heart-Shaped Deep-Belly Geometry:\u003c\/b\u003e Measuring 38.0mm in horizontal width paired with a full 40.0mm belly depth.
