These felt-tip pens are great for writing with several different colors because the tip is very thin and the colors really stand out well. Moreover, these pens hold long enough, careful though not to press the point at the risk of sinking or cut in half. Contrary to a comment posted here already, these pens do not pierce the paper, at least for me. This should depend on the quality of the paper (yet ... I do not use high-end paper!). Very good product.
