This is a guitar pick made from the highest-grade, rare wood, Brazilian Rosewood (Jacaranda). Jacaranda is currently listed as an endangered species under the Washington Convention, making it difficult to obtain. This material, seasoned for over 20 years (naturally dried), is used in high-quality, handmade guitars. It has a very beautiful grain. Please check the size in the photos. This is a one-of-a-kind, handmade item that cannot be mass-produced. The finish is oil-based. It has the unique, pleasant fragrance of rosewood (the rose-scented wood). 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.
