I frequently am away from my house on the weekends because my fiance lives about an hour away. Just for the weekend, is it safe to keep the smokes I bring with me in a ziplock with a water pillow or do I need something more substantial? Will they keep for a week in a ziplock with a water pillow? I am gonna end up buying a small humi to keep at her place in a little while anyway I'm sure, but I was just wondering for the mean time.
