Low humidity- yes, absolutely. No static charge at all.
Happens with all the stuff I buy online rn. I took my comic books with me in my backpack.
Thanks for the answer! Well, I can't just ignore the problem and do nothing... I will try to raise humidity little by little and check it with hygrometer frequently. I've bought a new one and it says my humidity lower than 20 %. I would like to buy expensive climate control system but well, I don't have so much money. Also I live in a apartment house so house humidifier is not a solution for me( I am going to move later this year, maybe I will think something up, just afraid the condition of my books will get worse.
