Advantages

The primary advantage of this marker lies in its versatile ink formula, which provides excellent coverage and vibrant color intensity on both porous and non-porous materials. Because the ink is water-based and non-toxic, it is safe for various environments.

When it may not be suitable

This marker may not be the best choice for covering large surface areas due to its extra-fine 0.7 mm tip, which is optimized for precision rather than broad strokes. Additionally, while the ink is durable, it may require a sealant or varnish if used on surfaces subject to heavy friction or outdoor exposure to ensure maximum longevity.

How to use

To begin using the marker, shake it well with the cap on to ensure the internal ball mixes the pigment thoroughly. Remove the cap and press the tip down onto a scrap piece of paper several times until the ink begins to flow into the nib. Once the tip is saturated, you can begin your work. Always replace the cap tightly after each use to prevent the ink from drying out.

What to consider before purchase

• Ensure the surface is clean and dry before application for best results
• Consider the need for a protective fixative if applying to smooth, non-porous surfaces
• Test the marker on an inconspicuous area if working with delicate or unusual materials

Usage recommendations

For optimal performance, store the marker in a horizontal position. If the tip becomes dry, you can rinse it with water or replace it if necessary to maintain the precision of your lines.
