Unused walnut bracelet (monkey head walnut). It has slightly stiff elastic rubber inside, so it has some stretch. The wrist circumference is about 17.5cm when not stretched. Please refer to the photos of it being worn on a 17.5cm wrist. Please note that it is made from natural materials, so there may be some irregularities. Although it is unused, it has been in someone's possession, so please refrain from purchasing if you are looking for a perfect item.
