COLNK CL640 Flexible Brush Tip Acrylic Paint Markers (16-Pack)

Bring painterly freedom and vivid color to DIY crafts with the COLNK CL640 Brush Acrylic Paint Markers 16-Pack. Equipped with responsive, high-elasticity synthetic nylon brush nibs, each pen effortlessly transitions from delicate 0.5mm calligraphic hairlines to expressive 4.0mm sweeping strokes simply by varying hand pressure. Engineered with an upgraded direct-capillary free-ink delivery system, these markers flow immediately upon uncapping, eliminating the mess of valve pumping, shaking, and accidental blotches.

Key Features

• Flexible Nylon Brush Nib: High-resilience synthetic brush tip mimics traditional watercolor brushes, offering exceptional line-weight modulation from 0.5mm detail work to 4.0mm broad color fills.
• Direct Capillary Free-Ink Delivery: Advanced capillary reservoir ensures instantaneous, consistent ink flow right out of the box—no priming, pumping, or shaking needed.
• High-Opacity Acrylic Pigment: Opaque, water-based acrylic paint dries quickly with complete opacity over both dark and light substrates, creating a uniform, matte, and fade-resistant finish.
• Permanent All-Surface Adhesion: Cures into a waterproof, smear-proof coat that bonds durably to river rocks, stretched canvas, wood slices, terracotta, glass, resin, and fabrics.
• Curated 16-Color Creative Palette: A vibrant assortment of essential primary tones, bright pastels, and foundational black and white for versatile crafting.
• Non-Toxic & Odor-Free: Formulated without harsh solvents or acid, strictly adhering to ASTM D-4236 and EN71 safety standards for artists, hobbyists, and classroom craft sessions.

Usage & Storage Guidelines

1. Uncap and paint directly onto your selected medium; no shaking or nib depressing is required.

Frequently Asked Questions

• How does the brush tip perform for lettering and fine lines?
  The tapered nylon brush nib holds a fine, sharp point for delicate contouring and hand lettering, while flexing easily under diagonal pressure for bold script downstrokes and quick filling.
• Do these markers require priming before painting?
  No. The CL640 series features a continuous capillary feed mechanism that provides ready-to-use pigment flow the moment you uncap the pen.
• Can these paint markers be used on outdoor garden stones?
  Yes. Once completely cured, the acrylic pigment is waterproof and weather-resistant. For long-term outdoor exposure to rain and sun, an acrylic clear coat sealer will maximize longevity.
