The permanent marker does not have a cap; the nib is extended or retracted by simply pressing on the push-button. Ideal for one-handed operation, e.g. when working up a ladder and holding a folding rule. The seal system prevents the marker from drying out when the nib is retracted. The high-quality ink is low-odour, waterproof and wear-resistant, and adheres to practically any surface; refillable with edding RMTK 25 refill ink. The practical clip prevents it from rolling away and can be secured to clothing and other objects. High-quality branded product, manufactured in tried-and-tested "Made in Germany" quality.
