glass mason jar, or a glass anything jar, such as the jars that jelly, spaghetti sauce comes in, just make sure you wash it good if food came in it, cuz weed seems to have this tendency to soak up "smells" in the air and turns them into "flavors" and usually it doesn't taste too good, but of course, i wouldn't mind making my own special spahgetti sauce using weed, that'd be pretty fuckin tastey, and you could get high off a joint or bong or something, get the munchies and get even higher
