How to use

Remove the cap and hold the marker at a moderate angle to the surface to produce an even line. For best results, write on clean, dry, smooth surfaces; test on an inconspicuous area if surface compatibility is uncertain. Replace the cap after use to reduce drying and maintain tip performance. If marking transparent or light-coloured projection materials, allow ink to dry briefly before handling.

Usage recommendations

Store horizontally or with the tip down for short periods to keep ink flow consistent. Keep the cap closed when not in use and avoid prolonged exposure to direct sunlight or high temperatures. Not suitable for porous surfaces where ink may bleed or for fabric unless permanent marker use on textiles is intended.
