What surfaces can it be used on?Answer: JiMiao marker pens use quick-drying, waterproof ink, making them suitable for paper, plastic, glass, metal, wood, ceramics, and other surfaces. However, adhesion varies depending on the material. On smooth surfaces like glass and metal, we recommend allowing the ink to fully dry or using a fixative spray for better durability.How durable is the marker ink? Will it fade over time?Answer: JiMiao marker pens feature high-pigment ink with strong light resistance, ensuring long-lasting color without fading, making them ideal for archival use and artistic creations. Under normal conditions, the ink remains vibrant for years. However, prolonged exposure to high temperatures or strong UV light (such as outdoor use) may cause slight fading. To extend color longevity, applying a clear protective coating is recommended. How can we help? Type your question. SubmitStart Over If you are human, leave this field blank.
