I accidentally put a half inch red mark (from red ballpoint pen) on the inner lining of my Galliera in monogram canvas. How do I get rid of it? I tried using eraser, but it kinda smudged the ink further. A friend was telling me i can try using Mr. Clean magic eraser. Note: the inner lining of galliera in monogram canvas is made of leather-like materials in off-white/beige color (very light) as opposed to cloth-like materials (in brown color) in some other mono canvas purses. Please help!
