Handmade using natural wood (walnut). Because it is natural wood, the color and grain will differ, and no two items are exactly alike (one-of-a-kind). Due to being handmade, there may be gaps at the joints or areas that are not perfectly smooth. The cord is synthetic leather and the length can be adjusted. Size: 40mm (H) x 40mm (W) x 7mm (D) Materials: Natural wood (walnut, padauk)
