Colorful, continuous knotted loops. Handcrafted, so each set is made uniquely for you! Nickel free. Cotton cord; sterling silver plated, gold, or rose gold plated brass/stainless steel. 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.
