Well, that was quick!

Probably an automated response... I was on the LA Police Gear website looking at these:

Hazard 4 Blood Type Lacer 2-Pack

and these:

Mil-Spec Monkey Bloodtypes Patch

  and saw these:

Mil-Spec Monkey Sulfa Allergy Patch; also available in penicillin, morphine, and latex.

Subject: Allergy patches?

Have you considered making allergy warning tags like the blood type lacers? Sometimes a medic alert bracelet is impractical, and I think these would be more versatile than the velcro patches your competitor sells, and (based on the highly scientific survey of HH6) look better too.
