This one is near-n-dear to my heart. As a gag for office decor, I tried ordering a "4, 4, 4, Radioactive" NPFA diamond several years ago. And uh... lets just say that stuff went sideways, fast.
Well, now I have one! And the patch commemorates the misadventure/hilarity of trying to obtain the first one! Turnaround was good for something so custom, and they understood my requirements to ensure the bottom special panel had a Radioactive trefoil symbol on it. Great job!
