How Can I Get Ballpoint Ink Stain Off Patent Leather Pocketbook?

Try spraying the inked area on the leather with hairspray and wipe it with a clean cloth.

You can also use a vinegar and water solution and a soft cloth but I don't know the proportions of vinegar to water. There is a book that you can find online that will help you with that by TipKing called "Great Uses For Vinegar".

If you still can't get it out talk to someone at a local leather outlet.

I just used alcohol to remove ink off most things. It simply dissolves it.
