I do these bits and bobs up on epaulet shaped card stock and they look great.  They're a nice way to display your pieces.  These represent a General Service Lieutenant Colonel of the Canadian Army.  The pip is 21mm wide.  Button is 14mm.  All cross pins are included for title and pips.  Button has it's long wire folding tabs in place.

Good luck and thanks for looking at one of The Mighty Atom's sales.
