How to use

Shake the marker gently before use to ensure uniform ink flow. Remove the cap and test the tip on a scrap piece of material to confirm ink flow and line thickness. Apply consistent light pressure for fine lines; increase pressure slightly if a darker, broader stroke is required. Replace the cap securely after use to prevent the tip from drying out. Store the marker horizontally or with the tip down for short-term use to maintain readiness.

Usage recommendations

For best results, use on clean, dry surfaces and allow ink to dry completely before stacking or handling. Avoid prolonged exposure to direct sunlight or extreme moisture to preserve ink visibility. When marking non-porous plastics or glossy surfaces, test on an inconspicuous area first to confirm adhesion and dryness time.
