This is a guitar pick made from a special, highly valuable 100-year-old Brazilian rosewood (Jacaranda) – the highest-grade, rarest wood. Jacaranda is currently listed as an endangered species under the Washington Convention, making this wood extremely precious. This Jacaranda was sourced from the beams of an old Brazilian building and is 100 years old. Please check the photos for the size. This is a one-of-a-kind, handmade item that cannot be mass-produced. It has the distinctive, pleasant aroma 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. ★ Available for sale at Kaminari Guitar Shop, near Motomachi-Chukagai Station on the Minatomirai Line in Yokohama, Kanagawa Prefecture. ★ Will be exhibited at Yokohama Music Style 2026 at Osanbashi Hall in Yokohama, Kanagawa Prefecture on March 28th and 29th, 2026.
