The Stabilo Point can be used as a writing instrument well, because it slides well on the paper. If the pages described are kept in the dark, you can still read it even after years. Unfortunately we have to Stabilo Point used and found that the light-exposed images are no longer black over time, but blackish yellow, green, red or blue also to draw. Which black tone arises, you can not imagine, because that is different from package to package. If one uses unintentionally at different dealers selling pens may arise unintentionally as more blacks when exposed to light and it looks a bit unsightly. Illustrations by artist friends lost so much color, that I first installed on walls with little natural light and finally ausrahmte because only yellow lines were left and it was feared that eventually nothing can be seen. Fair to an indication of the print pins, which warns that they are not lightfast.
