It was a childhood circumcision, freehand, so the scarline was very well visible originally. After 30 years, the "railroad" pattern, the sewing trace, began to fade, and for a long time there was a hole in the skin, next to the scarline, the trace of the last big stitch, it grown down. After 50 years, the scarline can only be seen very closely. Maybe the Gomco rings stay much longer visible.
