Pen marks on leather are hard to remove. You might search the Coach Rehab and Rescue thread for suggestions and lots of tips on rehabbing:Thanks for the tips, Catbird9.
Could you suggest if anything can help fade out old pen marks? (Part of the reason why I was so bold with washing the bag before knowing anything about rehabbing is because of some pen marks the seller missed/forgot to disclose.. The blue pen marks are on the top and front of a tabac tan bag.... :s) I suspect the answer might be no but I’d really appreciate any suggestions. Thanks!
