I’m a first aid nerd that taught Red Cross first aid for years. I’ve got lots of kits for different purposes.
WALLET: A couple bandages (biggish, good adhesive), alcohol wipe packet or two. Mostly to keep small wounds from bleeding on stuff or getting dirty.
EVERYDAY BAG: Basic pocket size kit sometimes with a few meds, repair items, a scalpel blade, good tweezers, etc. This kit is mostly meant to deal with daily owies or annoyances.
My bigger kits are home and car based, and the car kit can be quickly converted to a field kit with some trauma supplies.
