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?
Sakura Koi Colourbrush pens are not designed to be refilled. They are intended for single-use and should be replaced when the ink runs out.
How do I achieve different line widths?
Vary the pressure applied to the flexible foam tip. Lighter pressure and using the tip's edge creates finer lines, while heavier pressure allows for broader strokes.
Are these pens waterproof once dry?
No, the water-based dye ink is not waterproof. It can be reactivated with water, which is useful for creating watercolor effects but means it is not suitable for permanent line work without fixing.
What is the purpose of the Blending Pen?
The Blending Pen is a colorless marker that can be used to lift and blend existing ink on the paper, allowing for smoother gradients and subtle color transitions without adding more pigment.
How long will the ink last?
The lifespan of the ink depends on usage frequency and storage. Stored properly, they should last for a considerable amount of time for regular art use.
Can I use these pens for calligraphy?
Yes, the flexible brush tip allows for creating variable-width strokes, which are characteristic of brush calligraphy. However, practice is needed to master the technique.
Troubleshooting
Pen is not producing ink or is skipping.
Ensure the cap has been removed properly. Store pens tip-down or horizontally. Gently scribble on scrap paper to reactivate ink flow. If the tip is dry, try moistening it slightly with a damp cloth (do not soak).
Ink colors are not blending smoothly.
Ensure you are working on appropriate paper (smoother, heavier stock is better). Use the Sakura Koi Blending Pen for optimal results. Try blending while the ink is still wet, or use a waterbrush for a softer effect.
Ink appears too saturated or blotchy.
Use lighter pressure and multiple thin layers rather than one heavy application. For watercolor effects, use a waterbrush to dilute and spread the ink after application.
Tip is damaged or frayed.
Handle the pens with care, avoiding excessive pressure that could deform the foam tip. If the tip is significantly damaged, it may affect line control and require replacement of the pen.

Setup, Compatibility & Care
Setup: These pens are ready to use straight out of the package. Ensure the cap is securely replaced after each use to prevent the tip from drying out.
Compatibility: The Sakura Koi Colourbrush pens work best on drawing paper, watercolor paper, or mixed-media paper. They can be used with waterbrushes for watercolor effects and are compatible with the Sakura Koi Blending Pen for advanced blending. For best results with blending, use a smooth, heavy paper that can handle moisture without buckling excessively.
Care: To maintain performance and longevity:
- Store Properly: Always store the pens horizontally or with the tips pointing downwards to ensure consistent ink flow.
- Cap Tightly: Secure the cap immediately after use to prevent the ink from drying.
- Clean Tip: If the tip becomes clogged with dried ink, gently wipe it with a damp, lint-free cloth. Do not use solvents or harsh cleaning agents.
- Avoid Over-Saturation: While designed for blending, avoid excessively saturating the paper, especially with lighter weight papers, to prevent damage.
