My friend bought her first LV bag over the weekend end.(I was with her) We were so exited, We didn't check on the bag while we were in LV shop. Then... When she got home she called me. There's a little red spot on the hand strap!!! She couldn't get it out! It's the red spot that came with the dust bag. I told her to use lotion to rub it...That doesn't work either! We desided to return it,They could not accept the bag because of that red spot....... What should I do to help her??? Can anyone help.....
