This pendant comes with a nylon cord hand-woven by the carver. These cords are very durable, allowing you to safely wear your pendant 24/7 if you like (even in the shower). However they do wear over time and will eventually need to be replaced. Even so, a person who lives a vigorous lifestyle can reliably expect their cord to last at least two years; and a person living a quieter life can expect their cord to last a lot longer.
