Vegetable-tanned leather, leather bracelet width 0.8cm, thickness 5mm, length (wrist circumference) 19cm. Brass is used for the clasp. For reference, we have posted photos of the aging (color change) of vegetable-tanned leather. We hope you will maintain it yourself and bring out a good patina. We can also make it in longer or shorter sizes, so please comment if you wish. ★No need to comment before purchasing★ ★No price negotiation★ We think it will pair well with items like Goros! (!^^)!
