The corpus is the body of Christ that would be part of a crucifix if he were to be situated on a cross. This piece allows you to create your own crucifix of wood, polymer or any other medium you choose.
The front of the component is the same as any crucifix. The back features spikes behind the hands and feet of Jesus - to attach the corpus, or body, to the cross. We're showing the front on the left and the back on the right in the photograph.
The corpus measures 5/8 inch wide by 7/8 inch long. The spikes are about 3/16 inch.
