here is my problem. i bought a pack of pens. when i write in circles or just straight lines without any pressure the inks comes out just fine but the second i try to form words/numbers/shapes the ink stops flowing or flows for maybe a second or two but stops. it seems to do this off and on at random. i've tried 8 different pens they all do the same thing. they are just regular pens nothing fancy what is going on? is it because they are a cheap pack of pens? is it because my room is extra dry due to being on the second floor and getting in more heat than other floors? i dont leave the caps off. its getting to the point where im going to either start writing in marker or using some other means to write....
