Used Starbucks 24oz Barbie Pink Tumbler

PLEASE READ! Used Starbucks 24oz Barbie Pink Tumbler. I am the second owner of the cup. This cup has no dings. All paint is in tact. No chipping. The only thing that is wrong is it looks like maybe nail polish or marker at the bottom of the cup. SEE PIC 3. I never used the cup. I did wash when I received but never tried to remove what was on it. I did display it with a cup bumper and it did cover the mark. I am pretty firm on the price. I’m willing to come down some IF ur interested in another item I have listed and want to bundle. If u have questions please ask. Thank you
