Pilot Iroshizuku Ku-Jaku provides 50ml of dye-based peacock teal ink for fountain pen maintenance. Within the glass bottle, the wet, smooth-flowing liquid prevents hard starts on varied paper types. Dry times average 20 seconds to minimize smearing during fast writing.
Key Features
- V-Shaped Glass Reservoir: Hand-blown bottle with an ergonomic internal bottom. Extracts the final milliliters of ink when the supply runs low.
- High-Shading Chemistry: Dye-based formula reacts to paper absorbency. Produces distinct light and dark teal tones within a single pen stroke.
- pH-Neutral Composition: Non-corrosive fluid safe for vintage and modern luxury pens. Prevents damage to delicate ink sacs and internal piston seals.
- Wet Flow Rate: Optimized viscosity for consistent delivery through fine or broad nibs. Resists clogging despite the high humidity in BD that slows ink evaporation.
Frequently Asked Questions
Is Pilot Iroshizuku Ku-Jaku waterproof?
No, this dye-based ink lacks water resistance. Exposure to rain or spills will cause the peacock teal pigment to bleed immediately.
How long does Iroshizuku ink take to dry?
Drying requires approximately 20 seconds on standard paper. Coated or non-absorbent surfaces will extend this time significantly.
