Just have a look around man, there's actually a review on this thing.
From the review found here:

"It is VERY easy to do with the gimmicks provided, now it says you will never run out, but i see that to be a lie. may be its just me, one of the gimmicks you will not run out of, but the other you will sooner or later depending how much you do these effects. You will have to make yourself actually Cry for this effect, but it is very easy with the gimmicks provided. The refill on the gimmick is not hard to find around where I live, although that may very for where you live.
The Gimmicks:
As Said above one of the things you will have to buy more of after a while depening on how much you do this effect.
The stuff not included in the package are not hard to find.
and very common. Probably found at a Wal-Mart or Target."
