I bought a bunch of birthday cards for all the birthdays I need to worry about for the next six months.
I also already filled them out. The material on two of them made it so that the ink smudged around quite a bit. It is a bit unsightly. The writing itself is fine and intact.
Is there a way to clean up the smudged ink without messing with the writing or the material of the card? A q-tip dipped in something, maybe?
There are commercially available ink erasers, they come in the form of pens. They should erase any ink in use for pens. If it's a ballpoint pen you are out of luck though.
