Angel Wings is a special creation for any who own them. Handcrafted, so each set is made uniquely for you! Nickel & lead free. Cotton cord; sterling silver plated or 24K rose gold plated brass. Most of my pieces are made to order and should be on their way within 5-10 days. Slight variations can occur due to handcrafting & kinds of cord, but I create with a perfectionist's attitude.
