These are the worse refills, EvER!!! I have the pretty pink polka dot multi 4
refill pen with this disposable ink. It makes me not want to use my pen because
the ink scratches and is not smooth at all. What a disappointment. I looked
forward to getting this pen and pretty colored (pink blue-black green and
purple) ink only to have it ruined by this horrible writing ink. What a JOkE!!!
