How to use

Remove the cap and shake the marker gently if recommended by the manufacturer to ensure uniform ink distribution. Apply the tip at a slight angle to vary line width between 1 mm and 3 mm depending on pressure and stroke. Allow a few seconds for the ink to dry before handling the marked surface. Replace the cap securely after use to prevent the tip from drying out.

Usage recommendations

Use on clean, dry surfaces for best results. Test on an inconspicuous area of plastic or coated materials to check adhesion and compatibility before marking large areas. Store horizontally or with the tip down if the manufacturer advises to keep ink ready for immediate use. Keep out of reach of children and avoid inhaling fumes in poorly ventilated spaces.
