Our Vietnam Veteran Patches are made from colorfast threads on heavy backing to keep their shape and good looks. Although most patches have an iron-on backing, we recommend that you sew them on for longer lasting results. These Patches are a great way to show that you are a Veteran. Or, they make a great gift for that special Veteran! These Patches measure approximately 4 inches. Your satisfaction is guaranteed, period. Usually ships within 4 - 7 business days.
