We have been asked several times recently if these marks are removable from Leather. The quick answer is no, they are an ink, they are not as permanent as Paint Pens however, they are not designed to be removed from the material. Having said that, if you are washing the product after marking, particularly using chemicals, the chances are that the marks will be removed. We suggest that you run thorough tests before using these Pens on a final piece of work.
