Scriptliner is a professional grade marking pen designed specifically for "ultra-fine lines and precise details", widely used in nail art painting, model coloring, illustration marking, and craft drawing scenes. The length of the bristles can reach 15-25mm, and a single dip can pull out a continuous straight line of 5-10 cm, reducing the need for repeated dipping. Elastic nylon/Collins based wolf hair blend, with strong rebound of the pen tip, effectively cushioning hand tremors, and even beginners can draw fine lines up to 0.1 mm. Typical applications: Nail art: drawing French smile lines, 3D petals, and starry sky gradients. Model: Gundam seepage line, aircraft dashboard scale, hand-held eye gloss. Illustration: Cartoon character hair strands, architectural perspective lines.
