Stabilo Power - the felt-tip pen with its intense color output for anyone who enjoys creating beautiful pictures with cool pens at school or at home with friends. Thanks to its extreme drying protection, the felt-tip pen does not dry out for up to 8 weeks without a cap (tested at 23°C and 50% relative humidity). It is therefore the ideal solution for maximum use. The ink is washable. The sturdy M tip has a line width of approximately 2 mm and is pressure-resistant, while the cap can be attached to the end of the pen.
