This premium stainless steel #6 nib unit, crafted in Germany, is offered in three nib sizes: fine, medium, and broad. It is designed to be compatible with BENU fountain pens from the Euphoria, Talisman, and Scepter collections (exclusive to GRAND Scepter pens).
To swap out the nib, hold the upper part of the old nib and the pen's feed, then unscrew the nib unit from the grip section. Securely fasten the replacement nib unit's nib and feed into the grip section. Be cautious not to grasp the sides of the nib to avoid potential damage.
Importantly, do not separate the nib from the feed, as this action will nullify the pen's warranty.
