We went with single-serving packages, like Medique offers on Amazon.
These have ALL the proper info on each, it’s easier to issue the proper amount for the right problem, each are water-proof and sterile from the others, and lastly each wrapper provides an easy place to record what’s issued — simply write name and date on the wrapper and put back into the FAK’s ziploc bag.
Yes, it costs a tiny bit more and there’s the litter issue… but compare to Phi-meals its trivial.
