For band-aides I'd suggest the fabric ones over the plastic style.
Then learn how to x-cut them for fingers and such. They hold better and last longer. Toss in a roll of electrical tape also. A million+ construction workers swear by electrical tape for 1st aid!
I kept yellow, red, and green rolls of electrical tape.
Red for Gonna need stiches.
Yellow for keep an eye on it.
Green for just stopping blood drips from getting all over.
