This Sterling Silver Scapular Medal comes with a 20" inch chain. The medal measures 7/8" in length by 5/8" in width. This medal would make a perfect gift for you or the prayerful person in your life. In 1910, Pope St. Pius X introduced a scapular medal which may be substituted in most cases for any of the various scapulars. Valid enrollment in the scapulars must, however, be made before the substitution.
