Any glass airtight container is the best for storage of your cannabis. Plastic although convinient at times, is actually charged with static electricity which pulls tricomes off your bud. Ever wonder why your plastic baggies are so hazy after a while? Take a close look at a hazy plastic bag with a magnifying glass and you'll see the thousands of tricomes that will not end up in your bowl. Using plastic is actually making your bud slightly less potent.
