The Brush nibs have been developed in two parts to protect the delicate soft tip end, so it does not get damaged with frequent re-filling action.  The official way to remove the nib is to remove the soft brush part first then with broad edge tweezers, or gloved fingers (to protect from ink stains) remove the hard core part of the brush nib, re-fill the pen, replace the hard core part of the brush nib and replace the soft delicate brush tip, the nib will continue to work beautifully.  This design feature  is unique to Spectrum Noir to protect the investment in brush nibs for the system, and to increase the longevity of the brush nib

Please Note: These brush nibs will not fit our classic markers.
