FAQs

What type of ink is used in these pens?

The Sakura Koi Colourbrush pens use a water-based dye ink.

Can I use these pens with a regular paintbrush and water?

Yes, you can use them with a regular paintbrush and water to create watercolor wash effects. For best results, a dedicated waterbrush is recommended.

How do I achieve different line widths?

Vary the pressure applied to the flexible foam tip. Light pressure creates fine lines, while heavier pressure creates broader strokes.

What are the colors included in the 'Sweets' set?

The 'Sweets' set includes Naples Yellow (#9), Coral Red (#205), Lilac (#123), Lavender (#238), Light Sky Blue (#237), and Peacock Green (#426).

Are these pens suitable for beginners?

Yes, they are suitable for beginners, but mastering the flexible tip and blending techniques may require some practice.

How should I store the pens?

It is best to store the pens horizontally or tip-up to ensure even ink distribution and prevent the tips from drying out.

Can I blend colors directly on the paper?

Yes, you can blend colors directly on the paper while the ink is still wet, or use a blending pen or a damp waterbrush for smoother transitions.

Troubleshooting

Ink not flowing or is faint

Ensure the cap has been properly sealed. Scribble on scrap paper to reactivate ink flow. Store pens horizontally. If used recently, the tip might be dry; try gently pressing it onto a damp (not wet) cloth for a few seconds.

Ink bleeding through paper

Use thicker, heavier weight paper (at least 100gsm). Reduce the amount of water used if employing waterbrush techniques.

Colors are not blending smoothly

Ensure you are working quickly while the ink is still wet. Use a dedicated blending pen or a clean, damp (not wet) waterbrush. Experiment with layering techniques on scrap paper first.

Foam tip is damaged or frayed

This can happen with excessive pressure or rough surfaces. Handle the pens with care and avoid pressing too hard. If the tip is significantly damaged, performance may be affected.

Pros and Cons

Pros

  • Versatile line weight control with the flexible foam tip.
  • Excellent for color mixing and creating gradients.
  • Can be used for both sharp lines and soft watercolor effects.
  • The 'Sweets' color palette offers a unique and appealing range of hues.
  • Portable and organized with the included pouch.

Cons

  • Water-based ink may bleed on certain paper types.
  • Requires practice to master the flexible tip for consistent results.
  • Blending requires additional tools (water, blending pen) for best effects.
  • Ink is not permanent once dry and can be reactivated with water.
  • Foam tip may be less durable than traditional brush tips over time.

Setup, Compatibility & Care

Setup:

  1. Uncap the pens and ensure the foam tip is clean.
  2. For initial use, you may need to gently prime the tip by scribbling on scrap paper until ink flows consistently.

Compatibility:

  • Paper: Best used with heavier weight paper (e.g., 100gsm or higher) to prevent bleed-through and buckling, especially when using water.
  • Tools: Compatible with waterbrushes and Sakura's dedicated blending pen for advanced effects.

Care:

  1. Storage: Store pens horizontally or tip-up to ensure even ink distribution.
  2. Cleaning the Tip: If the tip becomes clogged or you are switching colors, gently wipe the tip with a lint-free cloth. For stubborn ink, you can lightly dampen the cloth. Avoid excessive water, which can dilute the ink too much.
  3. Cap Securely: Always replace the cap immediately after use to prevent the tip from drying out.
  4. Avoid Harsh Surfaces: Do not press the foam tip excessively hard on rough surfaces, as this can damage the foam.
