Glossy, soft cord. The part that goes around the arm is 28cm. Width: Approximately 1.5cm. Can be used on both sides or one side. I think it can be used for mini pouches, mini bags, etc., in addition to smartphones. The color of the heart charm is reddish, but it's a dark pink. I am a handmade amateur, so there may be some imperfections, but thank you for your understanding.
