The Staedler dry highlighter I can really only recommend. I've been looking specifically for a highlighter pen, with which I can highlight text on very thin paper, as for example. In legal texts (loose-leaf) occur. Here, the color should not "press" on the following page. With classic highlighters the Frabe expressed through happy times, which is quite inconvenient. At the same classic crayons have too high opacity. About a friend I was made aware of the dry highlighter. I have 2 different meantime tried that. Faber Castel and from Staedtler The Staedtler are much better suited to make marks on very thin paper. The pins are substantially softer. The pins of Faber-Castel are significantly harder, so thin pages very easily einreizen.
