Pins are actually geschirrspültauglich (max. 50 °). Before the surface needs but really dirt and grease. As for the black pen outlines mostly needed these works no longer correctly after 2-3 repeated use. The color then runs past the side at the top, rather than into the tip. The color messes and can no longer be vermalt properly. The tip is increasingly misshapen and after the third application can no longer recognize the Painted. Only recommended for 1-time use and then only if the hand can be performed particularly quiet. The pins paint very wide lines and a narrow bar is impossible for me. So I advise the purchase from definitely!
