I have tried these pins are looking for pins of a small whiteboard (A3 and A4). All colors, including yellow, write clear and rich in contrast. The strokes dry instantly and blur not know if I over it pranks (shirt, sweater ;-)) with your hand or a dry cloth. Corrections are done quickly with a moistened finger. And whether I after a minute or a week with a damp cloth wegwische the texts and drawings - they disappear without leaving any residue, the board is white again. I'm excited.
