This is a special guitar pick made from 100-year-old, high-value, rare Brazilian rosewood (Jacaranda). Jacaranda is currently listed as an endangered species under the Washington Convention, making this wood extremely valuable. This Jacaranda was made from lumber from the beams of an old building in Brazil, dating back 100 years. Please check the photos for the size. This is a handmade, one-of-a-kind 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 comfortable 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.
