Oil-based marker Grand GR-25 White — permanent oil marker, model 160-1962

The Grand GR-25 White oil-based marker is a compact permanent marker designed to deliver opaque white markings on a variety of surfaces. It uses oil-based ink formulated for durability and resistance to smudging, offering clear coverage for labeling, industrial marking, and craft applications where visible, long-lasting white lines or fills are needed. The marker’s size and tip design provide control for manual application and precise line work.

Advantages

Oil-based ink provides strong opacity on dark and light substrates, drying to a water-resistant finish. The formulation is intended to maintain consistent flow and reduce clogging for reliable performance over multiple uses. Its compact design allows for handheld comfort and accuracy when making labels, marks, or decorative details.

Suitable for

• Labeling metal, plastic, glass and cardboard surfaces
• Industrial markings and workshop identification tasks
• Crafts, model making and DIY projects requiring white contrast
• Touch-ups and visible markings on dark-colored materials

Key specifications

• Ink type: oil-based permanent ink
• Color: white, opaque coverage
• Application format: handheld marker for manual use
• Tip: precision tip designed for controlled lines and fills
• Drying: quick-drying to reduce smearing on most surfaces
• Durability: resistant to fading and light mechanical abrasion once dried

How to use

Shake the marker well before use to ensure the ink is evenly mixed. Test on a scrap piece of similar material to check flow and opacity. Apply steady pressure and draw or write as needed, allowing the ink to dry fully between passes if greater opacity is required. Store horizontally or according to manufacturer guidance to preserve tip saturation and prevent drying.

Usage recommendations

For best results, clean and dry the surface before marking to improve adhesion and opacity. On very smooth or non-porous surfaces, allow additional drying time and avoid rubbing until the ink has set. Keep the cap securely closed when not in use to maintain ink quality and prevent tip drying.
