First aid kits are for the First Aid, folks.

“No problemo, just seal up all the individual contents and you’ll be good to go.” A reasonable way of thinking, but it overlooks a big issue – when you need a first aid kit, theres a pretty good chance you’re under stress, your hands might be a little shaky, and you may only have one hand to work with since your other arm/hand might be injured.
