Lesun Overseas 12 Blue Oil-Based Paint Pens — Permanent Waterproof Markers, Medium 2mm Tip

Lesun Overseas 12 blue oil-based paint pens are waterproof, quick-drying permanent markers designed to write boldly on almost any surface.

These oil-based paint pens deliver opaque blue ink that resists water and fading, making them suitable for crafts, repairs, labeling, and decorative accents. Each marker contains stable, non-xylene ink sealed inside a clear plastic barrel so you can see remaining ink. The pens come individually wrapped and feature a durable medium round tip that balances precision and coverage.

What surfaces will these blue paint pens work on?

Lesun oil-based pens are formulated to adhere to porous and nonporous materials alike — from paper and canvas to metal, glass and tyres. Because the pigment is opaque and permanent when dry, it stays visible on dark and slick surfaces.

• Glass, metal, ceramic and plastic — bold, non-transparent marks
• Wood, canvas, fabric and leather — permanent decorative accents
• Stone, rubber, tyres and outdoor uses — water-resistant results

How do I get smooth, consistent ink flow from the pen?

Proper priming makes the ink flow reliably. Shake well to mix the pigment, then tap the tip while holding the pen tip-up to evacuate trapped air; press the nib against a surface to saturate the tip before writing.

• Shake 20–30 seconds to fully mix the ink
• Press tip upward to release air, then downward to feed ink to the nib
• Test on scrap material until the blue colour writes evenly

What are the marker’s technical details and safety notes?

The pens use oil-based, quick-drying ink that is free of xylene and toluene and formulated to meet EN71-3 and ASTM D-4236 standards. The medium round nib (about 2.0–2.8 mm) offers roughly 2 mm line width for controlled strokes.

• Ink: oil-based, opaque, non-transparent and quick-dry
• Tip: medium round, approx. 2.0–2.8 mm for clear lines
• Packaging: individually heat-sealed to prevent leakage in transit

How do I remove marks or clean the tip if needed?

Once fully cured the ink is designed to be permanent and water-resistant; removal typically requires solvents. For uncured ink or to clean the nib, use mineral alcohol or turpentine as recommended for oil-based paints.

• Fresh spills clean with mineral alcohol or turpentine
• Cured marks may need mechanical abrasion or strong solvents
• Store capped and upright to protect the nib and prevent drying
