That was my experience as a kid, but using them as an adult that’s never the case. I think it was a combination of cheap pens and a child’s carelessness.
A “different” solution would be to write from right to left. I’ve tried it multiple times — both writing with mirrored symbols and writing non-mirrored symbols. The positive was that my hands were a lot cleaner. The negatives were that others couldn’t read what I wrote and that I looked as a crazy person.
