Medtainer.
OK grinder and big enough storage to put in a few nugs, some papers, a one hitter and a small lighter (or some matches).
Waterproof, air-tight and smell proof.
Only thing is over the course of a few months/years the keef forms into this annoying sticky layer of dark hash on the inside of the container/grinder, making it hard to open/close sometimes unless you stay on top of scraping it off.
I tested the waterproof-ness of it too a few times, falling in the lake or what have you.
Highly recommend, easily the best $20 grinder/container I ever bought.
