FAQs

What type of ink is used in these pens?

The Sakura Koi Colourbrush pens use a water-based dye ink, which is known for its vibrant colors and blendability.

Can I refill these pens?

These pens are not designed to be refilled. Once the ink is depleted, they are intended to be replaced.

How do I create watercolor effects?

After applying the ink to your paper, you can use a waterbrush or a clean, damp paintbrush to blend and spread the color, creating a watercolor wash effect.

What is the purpose of the blending pen?

The blending pen contains a clear, solvent-free solution that allows you to lift and blend colors on the paper without adding more water, enabling subtle gradations and color mixing.

Are these pens suitable for beginners?

Yes, the flexible tip and blendable ink make them suitable for beginners learning about color mixing and line variation, though achieving perfect blends may require practice.

What are the colors in the Botanic set?

The Botanic set includes: #31 Viridian, #29 Green, #226 Emerald Green, #27 Yellow Green, #130 Sap Green, and #47 Raw Umber.

How should I store the pens to ensure longevity?

It is recommended to store the pens horizontally to ensure the ink flows evenly to the tip. Always cap them tightly after use.

Troubleshooting

Pen is not drawing ink

Ensure the cap was securely on. Try gently squeezing the barrel to encourage ink flow. If the tip is dry, moisten it slightly with water and test again.

Ink flow is inconsistent

Store the pen horizontally. Check the tip for any dried ink clogs and clean gently with water as per care instructions.

Colors are not blending smoothly

Ensure you are working quickly while the ink is still wet. Use a waterbrush or the blending pen for more effective blending. Experiment with different paper types.

Tip feels damaged or frayed

Reduce pressure during use. If the foam tip is significantly damaged, it may affect line quality and blending capabilities.

  3. Cap: Always replace the cap tightly after use to maintain ink flow and prevent drying.
