Professional 50ml Rich Black Bottled Ink for Refillable Pens, Calligraphy & Creative Drawing

Bring the vibrant depths of the natural world to your desk with 07 Mallard Fountain Pen Ink from toms Studio. Far from a standard blue, this formula is a sophisticated fusion of deep teal and forest green. Aimed at nature lovers, creative writers, and illustrators, it offers a moody richness that ensures your sketches and letters stand out with distinct character and professional flair.

This water-based, non-toxic ink is meticulously crafted in the UK for a wonderfully free-flowing feel, eliminating the common issue of dry starts or stuttering lines. Because it is highly layerable, you can achieve varying intensities or dilute it with water to create beautiful, watercolour-like washes for artistic depth. Whether you're filling a classic fountain pen or a modern refillable fineliner, this acid-free and vegan-friendly ink provides a smooth, reliable flow for reams of creative output.

  • Intensely rich pigment
  • 50ml bottle 
  • Water-based formula is acid-free, non-toxic, and 100% vegan-friendly.

Tom’s Studio began in a Dorset workshop when founder Tom Gyr—a furniture maker and blacksmith—watched his wife, Gemma, struggle with mass-produced, disposable calligraphy pens. Using a 1960s lathe, Tom engineered a precision-balanced pen designed to last forever.

Today, this UK-based brand leads the "refill-ution," moving away from plastic waste toward sustainable, luxury stationery. Every fountain pen, dip pen, and bottle of pigment-rich ink is crafted with an artisan’s eye for detail. Perfect for artists and writers, these tools blend traditional craftsmanship with modern ergonomics to make every mark on the page feel effortless.

Excellent service. When it seemed the universe had decided I was not to receive my package, Sammy defied nature itself to ensure it arrived and I even got a badge. Couldn’t be happier. The artwork arrived well packaged and is beautiful; exactly as described.

This shop is fantastic - not just for the quirky and unique items that won't be found elsewhere but the service too (really friendly and attentive). I was looking for a special present but left with several, which were all massively appreciated.
