Octopus Fluids WD-PR-050-050 Write and Draw Ink 419 Petrol Buffalo 50ml

Versatile Waterproof Ink for Writing & Art

Octopus Write & Draw Ink is a premium waterproof and smudge-proof ink designed for both writing and artistic applications. Suitable for fountain pens, dip pens, nibs, glass pens, and brushes, this ink bridges the gap between everyday writing and professional drawing. Its fast-drying, waterproof finish makes it ideal for sketching, illustration, calligraphy, and creative colouring techniques.

Brilliant Colour Range with High Pigmentation

Available in 38 vibrant shades, the Write & Draw ink range impresses with intense colour depth and balanced pigmentation. The palette includes a deep black, multiple grey tones, and a uniquely opaque white that performs exceptionally well on dark surfaces. Each colour delivers strong coverage, clarity, and consistency, whether used alone or layered.

Engineered for Fountain Pen Performance

Special attention was given to fountain pen compatibility during development. The use of ultra-fine pigments and a carefully balanced formula ensures smooth, even ink flow without clogging the feed. Despite being a pigmented, waterproof ink, Write & Draw maintains the pleasant writing feel and reliability associated with classic Octopus fountain pen inks.

Document-Proof and Vegan Formulation

Octopus Write & Draw ink meets strict standards for document permanence in accordance with DIN ISO 12757-2 and DIN ISO 14145-2. It offers high light fastness and long-term durability, making it suitable for official documents and archival work. The ink is produced exclusively with vegan ingredients, reflecting a commitment to responsible manufacturing.

Exceptional Results for Writing & Calligraphy

Writing enthusiasts appreciate the razor-sharp text and attractive shading achievable on fountain-pen-friendly paper. Calligraphers benefit from the ink's ability to produce fine hairlines as well as bold, expressive flourishes. Urban sketchers and illustrators can rely on crisp, precise outlines that remain intact even after additional colouring.

Waterproof, Layerable & Highlighter-Resistant

Once dry, the ink becomes fully waterproof within a short time and can be painted over with watercolour or additional layers of Write & Draw ink. It is eraser-proof, and most colours are also resistant to highlighters, making it practical for notes, sketches, and mixed-media work where durability matters.

Flexible Colour Mixing & Watercolour Effects

Octopus Write & Draw ink performs beautifully both undiluted and mixed with water. Used pure, it delivers strong opacity; when diluted, it creates soft gradients and elegant watercolour effects. Colours can be mixed with each other or with water, allowing artists to create countless custom shades and tonal variations.

Safe Use with Proper Pen Care

Unlike many waterproof inks, Write & Draw can be used in fountain pens with confidence. However, pens should not be allowed to dry out, as the ink's waterproof properties rely on a cross-linking binder that becomes difficult to dissolve once dry. Regular rinsing and thorough cleaning after use are recommended to keep writing instruments in optimal condition.
