Ultramarine will produce a sheening effect on high-quality fountain pen papers like Tomoe River and Rhodia. The writing sample in this listing was produced on 68 gsm Tomoe River paper.
Fountain pen ink is manufactured by hand in the workshop from a series of raw ingredients selected for stability and performance. Our inks are compounded with diluent, thickener, humectant, lubricant, surfactant, preservative, and colorant. Ingredients are meticulously combined and refined over roughly two dozen steps with a minimum of three thorough mixing steps per color to ensure quality and consistency within every small batch.
The 60mL volume will provide approximately 75 standard converter refills with an average 0.8mL draw. Each jar is carefully poured and labeled by hand. Glass bottles arrive prepared in our beautifully foiled Birmingham Pen Co. gift box.
