[About the "Four-Ridged" Variety]
The "Holy Grail" for collectors. This ultra-rare mutation has four symmetrical ridges, creating a squarish, box-like geometry that is almost impossible to find in nature.

[Basic Care & Natural Aging Guide]
This collectible variety is grown strictly for hand-play (pan) and is completely distinct from common edible fruit variants. Through consistent contact with clean, bare hands, the high-density wood grain steadily absorbs natural skin oils. Over time, this natural interaction will cause the initial ginger-caramel wood tones to transform into a deep, glossy, translucent red-brown patina. Because the chiseled ridge paths are exceptionally deep and tightly woven, it is highly recommended to brush the crevices thoroughly with a standard bristle brush after each use to keep the valleys immaculate.
