Shall I go and accept my coach casino bag that has few pen marks cost $45

Yesterday I just received my coach casino bag I ordered online and i think with the price I paid it is good enough and it's hard to decide because it is cute. But except on the few pen marks I discovered on the inside of the back slip pocket and the seller said it has no tear and stain.
 
Since you call this a 'casino' bag, I'm assuming it's vintage. Ink is a particular hate of mine. It looks like you can't see the marks when the pocket is in a normal position. They look light, and may lighten more if you rehab the bag. I vote to keep it, but try to clean it. Here's a link to the rehab thread, with lots of helpful information about dunking and conditioning vintage bags:


There are thousands of pages here, so you might want to search 'dunking' 'conditioning' and maybe 'ink marks' within the thread.
