Currently I carry in my wallet two plasters, an antiseptic wipe and some pain killers including aspirin so i can give it to someone having a heart attack (hope i never have to) in a small 2″x1″ ziplock type bag.

I was wondering you guys had any suggestions of what else i could carry in my wallet first aid it needs to be as low profile as possible as I hate bulky wallets and also needs to withstand back pocket carry (being sat on)
