I use a pump brush. I've bought mine from Nicholas Lodge, but Cal Java also sells them. I'll try to post the link....http://www.caljavaonline.com/tools1-pbrush-lg.htm
I love it!! I have about 4 of them, and have my pearl dust, gold pearl dust, and silve disco dust in them (one is still empty).
Edited to add:
Don't forget to take the little piece of black 'foam' out of the end up it, or you'll end up cursing yourself. (ask me how I know this, lol)
