A small gatorade mix container (orange and ribbed) lid make a great portable place to break up weed, and my glass pipe even fits inside it, i also keep my half-spent weed in the bottom, or when i clean it out i make it a munchy container and put my seeds in it, cannabis seeds are the best, you get a collection of them and then when you're dry you just munch on them and it gives you a buzz (prolly not for real just a placebo effect)
