Pilot Signature Fountain Pen Ink Bottle 30ml

The Pilot Signature 30ml Ink Bottle is a reliable, high-quality ink designed for smooth, consistent writing with all Pilot and Namiki fountain pens, offering easy refills and a well-behaved formula that resists clogging and drying.

It is available in 3 colours and supports both cartridge and converter filling systems, making it a versatile choice for everyday use.

Ideal for Daily Use
The Pilot Signature ink is engineered for dependable performance, delivering a smooth flow that suits regular writing tasks without skipping or hard starts.

Its water-based formula ensures compatibility with a wide range of fountain pens, particularly excelling in Pilot models where it maintains consistent ink delivery. This makes it a practical choice for journaling, note-taking, or correspondence where reliability matters most.

Balanced Drying and Flow
Unlike highly saturated or slow-drying inks, the Pilot Signature line offers a balanced drying time—typically under 30 seconds on standard paper—minimising smudging while avoiding overly dry performance.

The ink flows evenly without excessive bleed-through on most paper weights, including 80gsm and above, supporting a clean writing experience. Its low maintenance profile makes it ideal for users who prioritise convenience and functional performance over dramatic shading or sheen.

Simple Refilling and Maintenance
Refilling is straightforward with a converter: simply immerse the nib unit, operate the converter mechanism, and wipe clean before reassembling.

The 30ml glass bottle provides approximately 10–15 full fills for a standard converter, offering good value over time.

Regular flushing with water every few weeks helps maintain optimal flow and prevents clogging, especially when switching colours or after periods of inactivity.

Professional and Practical Choice
Available in classic shades like black, blue, and blue-black, the Signature ink maintains a professional appearance suitable for office or academic use.

While it lacks the intense visual effects of premium lines like iroshizuku, its predictable behaviour and clean lines make it a trusted option for those who value consistency and ease of use.

It pairs especially well with Pilot’s Metropolitan, Kakuno, and Custom series pens, enhancing their reputation for everyday reliability.
