This is a special guitar pick made from 100-year-old, high-value, rare Brazilian rosewood (Jacaranda). Jacaranda is currently an endangered species under the Washington Convention, making this wood extremely valuable. This Jacaranda was made from a 100-year-old beam from an old building in Brazil. It has a beautiful grain. Please check the photos for the size. This is a one-of-a-kind, handmade item that cannot be mass-produced. It has the unique, pleasant fragrance of rosewood (the "rose-scented wood"). The finish is oil-based. Please experience the pleasant feel of the wood that seems to cling to your hand. ★Please see my profile. ★Now on sale at Kaminari Guitar Shop, near Motomachi-Chukagai Station on the Minatomirai Line in Yokohama, Kanagawa Prefecture. ★We will be exhibiting at Yokohama Music Style 2026 at Osanbashi Hall in Yokohama, Kanagawa Prefecture on March 28th and 29th, 2026.
