A marker filled with quick-drying, lightfast ink, suitable for writing and drawing on whiteboards. The marker does not have a cap. The push-button mechanism allows for convenient one-handed use during presentations or note-taking. After use, pressing the push button retracts the tip and at the same time a special mechanism in the marker body seals it, preventing it from drying out. The writing can be easily wiped off dry from virtually any non-absorbent surface, such as enamel or melamine. Does not contain butyl acetate. Thanks to the practical clip, the marker does not roll away and can be attached to a pocket. Easy to refill with the Edding RBTK 25 capillary system. Line width of the rounded tip: 1.5-3 mm.
