marianas

Tom's Studio Marianas is a deep navy blue fountain pen ink inspired by the Mariana Trench, offering excellent color saturation and smooth flow suitable for all fountain pens. British-made with water-based, acid-free, and vegan formulation, it dries quickly in approximately 30 seconds and features a subtle pink sheen with low shading. The ink is highly layerable and can be diluted with distilled water to create watercolor-like effects, making it ideal for writers, artists, and calligraphers seeking a distinctive, well-behaved blue ink.
