Note that you only need sterile pads as the first covering over a wound. Once the wound is isolated with one or two of those, you can stack on the much cheaper "clean" gauze pads to absorb blood or whatever.
I'm not sure why you'd need sterile gauze. You cover the wound with a sterile pad, and then the gauze just holds the pad(s) in place. "Clean" gauze is good enough, your don't need the expense of sterile.
It would be difficult to list every first aid item I have. I have two ten packs of 4" x 4" gauze.
I have two 2" rolls of CoFlex. Do I need more?
