What's left of a new ouncer + new grinder

[MaryjaneAndHashley]

Nice bud. That grinder would be the same as mine if it had more teeth. Nice.

cool, and umm I wanted to know something. What if the kief collects in the chamber and then lets say I put it in my bag (the grinder) and well it bangs a bit on other stuff.. will the kief go back through the screen or what?
