If you don't have any pods, and this is only a temporary fix , use Mason Jars. If you have the regular size, the mouth fits perfectly in the Tippmann Gryphon gun gravity fed hopper. I would not use them in games (which is a bummer) because of the risk of breaking, and like I said, it is only a temporary solution. I would only use it for target practice. If you don't want to keep refilling your gun with the bag every time, just keep a jar fill of bullets when in need for a refill. It holds about 100 paintball bullets at a time.
