The pendant measures 5/8 inch tall and a half inch wide or 1.5875 x 1.27 centimeters. The front says " O Mary conceived without sin, pray for us who recourse to Thee". The back is not plain so we can not engrave it. This item is made to order so please allow about 4 days before I can ship it. I will provide a pendant box.
