Think of them like pre set mastery points, perhaps. You buy it, it's your forever (unless you combine it) .You place it in your rune page, you get the bonus. If you want, you can remove it from the page, and you get it back in your collection.

Also, for each rune page, you can reference the whole set you have bought. For example. Let's say the rune build you want for Champ A contains 4x of rune C and 9x of Rune D. Your Build for Champ B contains 5x of rune A and 7x of Rune D.  You would need 5x of Rune C and 9x of rune D in order to do what you want for each champ.
