With these pens it is essential to remember to open the cap always in a vertical position, and never to close it without having first retracted the nib inside the barrel, to avoid damaging the tip. Since this was a common drawback, some models (the first introduction of this innovation is attributed to Montblanc) require the presence of a special safety mechanism (usually a pin mounted in the center of the cap that beats on the nib assembly), which thus prevents it from closing if it has not been completely withdrawn inside the body of the pen.
