When refereeing for soccer, do I use my own AR flag, or does the ref always give his AR flags to the AR's?

Question

Because the AR flags are always the same for both AR's but I thought you provide your own flags.

Answer 1

I was given a pair when i ref'd but the center ref always let me use his.  

Answer 2

you should always bring your own flags, just in case the referree forgets his, but the center ref is supposed to have them before a game
