Each cross measures around two inches in length and 1¼ inch in width. A single Disciples Cross Necklace consists of three main parts - nails, twisted wire, and neck string. Four nails form head, feet, and arms of cross. These nails are symbolic of spikes driven into hand and feet of Lord Jesus. Twisted wire symbolizes crown of twisted and thorny branches and neck string is for leather straps used to beat up Jesus.
