Corps badges were not soldier arts and crafts projects.  Badges were purpose made, die cut, and for the common enlistedman they were an issued piece of clothing.  Many, especially the earliest versions issued to the Army of the Potomac in 1863, were made from crudely bent knife stock dies creating rather rounded corners.  These corps badges are matched to surviving issued originals in size, material, and color, and are die cut just like the originals.  They can be ordered individually or in lots of ten.
