NIMIX´s flags are presented in a long strip including both sides of one particular flag. So you will be able to make one or two flags, depending of the sides of the flag that will be visible.

Then, introduce the flagpole in its place and fix it. If the flagpole has a pike or other separate element at its end just leave the space on the top to introduce it after fixing the flag, they will match perfectly.The etched brass flag includes a design in the center to encircle the flagpole. However you can eliminate it if you want to make it different, with ribbons, for instance.
