These are great to throw in different daypacks and vehicles. They are a little bit much for an ultralight kit and a bit small for a Camp First-Aid Kit, but for the price and easy of setting up, these are great.
Get a premade economy kit such as one from First Aid Only (sold at Costco and Amazon). You can find one for under $20. You get a lot of medical supplies for a small priced. Augment it with what it lacks and you'll have a pretty decent kit.
Add the following:
3 or 4 inch rolled gauze
Small roll of duct tape
Wound Closure Kit
