We use only the highest quality freshwater pearls and premium rolled leather cord. Leather is a natural skin and will dry out over time if not conditioned regularly. If you wear the pieces all the time, the natural oils from your skin will keep the leather soft and strong. If you wear them only occasionally, you can condition the leather with shay butter which is available in our store or at your local drugstore. This will keep it soft and strong. If you have any problem with one of our products, please contact us immediately. Your satisfaction is our highest concern.
