This marker does not require a cap, which means that there is no cap that can get lost. The nib can be comfortably retracted at the push of a button. Thanks to a novel sealing mechanism it is air-tight and secured against drying out. Therefore, the pen can be used single-handedly. The ink can be filled up through replacement cartridges so that the marker can be used for a long time.
