This pack of 5 Darwi MARBEL replacement nibs restores a clean, even paint flow to compatible 4 mm markers when the original nib has become worn or contaminated. The replacements match the original format.

Change the nib over a protected surface and allow the new nib to absorb the paint gradually. Test the marker on a spare surface before returning to the final piece.

Rinse a used nib with clean water while the paint is still wet. Allow it to dry completely before storing or refitting it, and close the marker securely after use.
