Thank you for your interest in metal EMT EMS Emergency Medical uniform pin. Nice quality blue and white flow enamel with silver-chrome borders and measures 15/16” in diameter. It has two clasp pins on the reverse for easy and secure attachment to uniforms, clothing, gear, hats, etc. New, never used. Only removed from the manufacturer's packaging to take the photos for this listing. Please let me know if you would like any additional information. Thank you.
