Surprisingly enough, LiPo Safe bags can rather be more dangerous than something to increase safety. Most cheaper brands - and let's face it, some of use do have them, do not have an inner lining above the fibreglass cloth that all bags have anyhow. Have is happened to you that when you reach in the bag for a battery, it stings? Or have you had a bag go old and thus the cloth inside scratched, or destroyed a bit; and so you'd get the same sting, even harsh? Fibreglass is dangerous as I see it. What do you think?
