Step-by-Step Guide: Step 1: Cleaning and Polishing: Clean and, if necessary, polish the surface of the painted workpiece. A smoother surface enhances the gloss effect. Step 2: Pre-Use Shaking: Before each use, shake the pen (with the cap on) several times to ensure even distribution of the ink in the barrel. Full shaking ensures well-proportioned painting lines. Step 3: Air Exhaust (On First Use): With the pen tip upwards, press it to exhaust air from the pen tube and release pressure, especially on the first use. Step 4: Test Paper Preparation: Press the pen tip several times on test paper, allowing the paint to soak the pen tip. After soaking, cover the pen cap and let it stand for 5 minutes to soften the pen tip. Step 5: Closing and Storage: Close the pen cap promptly after painting, and it is recommended to store it horizontally. Patience is key—let it stand to expect optimal results. Tips: Avoid Eye and Mouth Contact: Be cautious to prevent ink from coming into contact with eyes and mouth. Age Recommendation: Not suitable for kids under 3 years old. For preschool children, use under adult supervision. Shaking with Closed Cap: Shake the marker while keeping the cap closed to prevent desktop and workpiece contamination. Erasing with Alcohol: For some non-absorbent surfaces, use alcohol for modifications during painting and drawing. Varnish Application: After the paint fully dries, consider applying a water-based varnish for added protection and gloss.
