Good paper for lining up, some of Pens and markers been through a little to the other side but I am heavy handed (a newbie). Also one of my pilot parallel pen inks feather (which others I note dont seem to have this issue). I have since ventured out to buy new ink for my Pilot parallel pens- Kon-Peki Iroshizuku and Herbin Perle noire and have had not uch issues with feathering or bleeding. I really enjoy using this paper.
