Staedtler Watercolour Brush Pens - Pack of 18

No, these pens are not refillable. They are designed as disposable pens.

Watercolour paper or paper suitable for water-based media is recommended for best results.

While these pens are designed for use on paper, testing on other surfaces is recommended. The ink may not adhere well to all surfaces.

Apply the ink to your paper, then use a wet brush to blend and spread the colour, creating soft transitions and washes.

The brush tip is designed for broader strokes and calligraphy, with a line width between 1 and 6mm. The fine tip is ideal for detailed work and fine lines, with a line width between 0.5 and 0.8mm.

The lightfastness of the colours may vary. It's recommended to store artwork away from direct sunlight to preserve the colours.

Store the pens horizontally to ensure even ink distribution and to prevent the tips from drying out. Always recap them after use.

Ensure the cap is tightly closed to prevent the pen from drying out. Store the pens horizontally. If the issue persists, the pen may be nearing the end of its ink supply.

Try gently reshaping the brush tip with your fingers or on a smooth surface. Avoid pressing too hard while using the brush tip.

Use thicker paper suitable for watercolour or water-based media. Apply less ink or use less water when blending.
