How to use

Shake the bottle gently before use if pigment settling is suspected. For pen refilling, follow the pen manufacturer’s instructions to avoid overfilling; transfer ink using a syringe, pipette or the pen’s built-in filling mechanism. For dip pen or brush work, pour a small amount into an inkwell or palette well to control exposure and reduce contamination of the main bottle. Close bottles tightly after use and store upright in a cool, dry place away from direct sunlight.

Usage recommendations

Test the ink on scrap paper to confirm flow and drying characteristics with your chosen tools and paper. When combining with other media, allow the ink to dry fully to assess compatibility with washes or fixatives. Dispose of empty bottles according to local waste regulations.
