I bought a patch for my sulfa allergy in preparation for the worst case scenario, God forbid we end there. I bought from Tactical Outfitters because of the price. If the quality was bad, is only be out a few bucks. I also bought a penicillin allergy patch for a friend of mine. To my happy surprise, both patches are magnificently made. They're embroidered very well and they don't have any signs of fraying or any loose threads. I'm very pleased with how they turned out.
