How to use

Ensure the marker is compatible with 6 x 15 mm square nibs before installation. Remove the old nib gently by pulling it straight out of the marker barrel; use tweezers if necessary. Insert the new square nib with the flat face aligned to the marker housing until it seats firmly. Test on scrap paper to confirm ink flow and stroke width, and allow a short adjustment period if ink distribution needs to stabilize.

Usage recommendations

Store spare nibs in a dry, dust-free container and avoid prolonged exposure to direct sunlight to preserve nib structure. For best results, use inks and marker bodies recommended by the marker manufacturer to maintain consistent flow and prevent premature wear.
