24 Colors Shimmer Markers Super Squiggles Outline Markers Set Double Line Outline Pens Self Outline Metallic Markers for Drawing

The 24 Colors Shimmer Markers Super Squiggles Outline Markers Set is a collection of double-line outline pens designed for artistic and craft applications. Each marker features a unique dual-color effect, producing a vivid metallic silver line with a colorful border. This is achieved through a specialized ink technology that automatically generates contours. The markers utilize a wear-resistant, pressure-resistant chisel tip for fluid and smooth writing or drawing. The pigment-based ink is formulated to be waterproof, quick-drying, and anti-fading. The markers are certified as 100% non-toxic, odorless, and acid-free, making them safe for general use. For optimal performance, it is recommended to shake the marker with the cap on, then press the tip gently on the surface a few times to initiate ink flow. They are best used on heavy paper to prevent ink bleed-through. The set is suitable for a wide range of creative projects including lettering, greeting card design, poster making, painting, highlighting, and various DIY crafts. The markers should be recapped immediately after use and stored horizontally to maintain ink quality.
