I based my small FAK on a pouch made by Sawyer that they don't carry anymore. It has a mesh pouch on the outside where I keep my nitrile gloves and some ear plugs. (I carry this kit when I travel on planes, and the ear plugs + a couple benadryl = no more red eyes ). I need to post a picture, I suppose.

TheraTears is another brand that offers single-use eyedrop containers. Works well for me in a small FAK.

For a CPR barrier, there are many keychain-sized units, but the one I've found most convenient for EDC is the Laerdal FaceShield. I carry one in my wallet and 1 in each of my small FAKs.

Otherwise, I've got pretty much the same stuff listed here.
