Before the cross became the universal symbol of Christianity, there was the Chi-Rho. When Constantine saw it blazing in the sky before the Battle of Milvian Bridge, he heard the words that would echo through history: In Hoc Signo Vinces — In This Sign, You Will Conquer. His soldiers painted it on their shields and marched into battle under the banner of Christ. Our Chi-Rho Lapel Pin renders that same ancient Christogram in a bold silver chrome finish, a battle-tested symbol of faith worn by warriors for over 1,700 years. Pin it on and carry the sign that conquered an empire.
