2. Correct posture: When holding the pen, maintain a correct posture that relaxes your hands and facilitates control of the pen's direction. Generally, the grip should be in the middle or slightly lower part of the barrel.
3. Writing and drawing: When writing or drawing, maintain moderate pressure to avoid using too much force that results in heavy ink or damaged paper. Pay attention to maintaining smooth and continuous lines. III. Advanced Usage Skills 1. Color matching: Learning to use different colors of marker pens to match can enrich your expression and highlight key points. For example, you can use different colors of marker pens to annotate different information or layers. 2. Thickness variation: By changing the force and angle of application, you can control the thickness of the marker pen, making lines more layered and three-dimensional. 3. Special effects: Utilize the special effects of marker pens, such as the waterproof and moisture-resistant properties of oil-based marker pens, to create more creative works. For example, you can combine water-based paints with oil-based marker pens during painting to achieve a rich color with no fading effect. IV. Usage Precautions 1. Avoid using marker pens on non-writing or drawing surfaces to prevent damage to the item's surface. 2. Clean the marker pen after use to prevent ink drying and affecting future use. 3. Do not randomly discard easily damaged items such as marker pen tips to prevent environmental pollution.
