The "Gundam Marker - Real Touch Blue 1" is a specialized marker from the Gundam Marker Real Touch series by GSI Creos (Mr. Hobby), designed specifically for adding weathering, shading, and realistic effects to your Gunpla (Gundam plastic models) and other plastic kits. Here's a detailed description: Purpose: Weathering and Shading: Unlike regular Gundam Markers that are designed for solid color application or panel lining, Real Touch Markers are formulated to create subtle, translucent effects. They are primarily used for: Shading: Adding shadows and depth to recessed areas, panel lines, and edges to make details pop and give parts a more three-dimensional look. Weathering: Simulating dirt, grime, oil stains, burn marks, or other realistic wear and tear effects on your model. Blending and Softening: The translucent nature allows for blending with the base plastic color or paint, creating smooth transitions and natural-looking gradients. Translucent Blue Finish: This specific marker, "Blue 1," provides a translucent blue hue. This allows the underlying color of the plastic or paint to show through, creating a layered effect that mimics natural shadows or subtle discoloration. It can be used to add a cool tone to white or light gray parts, or to simulate a faint blue grime. Water-Based Paint: A key feature of Real Touch Markers is that they use water-based paint. This makes them: Safe to apply over painted surfaces: Less likely to react with or damage existing paint jobs (e.g., lacquer or acrylics) compared to alcohol or enamel-based markers. Easy to blend and clean up: Since they are water-based, mistakes or excess can often be easily corrected or blended out using a cotton swab, tissue, or even a rubber eraser, making them very forgiving, especially for beginners. Dual Tips: Real Touch Markers typically come with two different tips: A fine tip: For precise application in panel lines, small details, or creating thin streaks. A broader, chisel-like tip: For wider shading areas, blending, or creating broader "smudging" effects. Realistic Effect: The "Real Touch" name emphasizes their ability to help modelers achieve a more "realistic" or "worn" look, moving beyond a clean, factory-fresh appearance. Manufacturer: Produced by GSI Creos (Mr. Hobby), a leading Japanese manufacturer of hobby paints, tools, and accessories, known for its extensive range of specialized modeling products.
