The Keystone Enamel Pin is a compact, industrial-grade accessory forged from antique gold-plated metal for a weighted and durable feel. Inspired by the strength of the architectural keystone, this 0.87-inch wide pin features a soft enamel relief and a high-density black rubber backer for a secure, non-slip grip. Designed to stay locked in place on any shop jacket or canvas cap, it serves as a reliable daily-carry artifact built to withstand the movement and grit of the daily grind.
