A glass jar, like a mason jar or a glass coffee jar is the best thing to keep buds in. It's usually pretty dry when I get it, which makes it easy to grind up, but then I put a small piece (1 or 2 inch square) of orange peel in after its ground. That way my joint doesn't burn too fast or too hot. Don't try to put it in a grinder after you put it in with the orange peel, it doesn't work.
