All our Military Pins have free shipping with tracking and come with a back. These are part of a large collection of thousands of pins. We will be adding more each day over the next few months. Please check back as we add more. Reach out if looking for a specific pin and we can create a new listing for you if we have it. Also due to having multiple quantities of some pins there could be minor differences when compared to the photo. Please ask any questions and we will do our best to answer them.
