Classic fountain pen inks


with extra smooth flow

Classic Collection

With the Classic collection, we at Octopus Fluids started to develop our first fountain pen inks in 2014 and launched an ink range in the creative sector for the first time. It therefore has a special significance for us.

Through continuous improvement and our growing expertise, we have refined the formulations and successfully overcome initial challenges such as feathering and bleed-through. Along the way, we have continued to add new, brilliant colours to the range.
Our Classic collection now offers a wide range of writing inks in 22 different colours, all characterised by even flow and beautiful shading.

The inks remain fluid in the pen for a long time, so you can write immediately even after a long break. On paper, our Octopus inks dry quickly.
We have developed a special formula for each ink colour. This is because the different high quality dyes used affect the properties of the ink so differently that only by tailoring the formula can perfect flow, shading and drying times be achieved.

Discover our Classic Collection - the perfect choice for discerning writers who value the highest quality and versatility, whether for everyday use or for exclusive fountain pens.
