It's very much depend on how much you use and how you stroke it.

I personally prefer maybelline specifically this:

2 tones. looks natural. and affordable RM 20+ below 30

they have it in bronze and pink.

Yeap, brush included.

You can use cotton bud? else you go make up store ie; sasa, guardian,watson to buy those small pack of cheap brush. For myself i will clean my eye shadow brush on a piece of clean tissue (dry) and re-use it again. make sure you clean properly. Else, you gonna look like panda/dirty.
