Van Dieman's Underwater - Blue Ringed Octopus - 40ml Fountain Pen Ink

Blue Ringed Octopus

Underwater Collection – 2026 Edition

New 40ml Bottle

The Blue Ringed Octopus is the most venomous creature in the world, living in the rock pools and shallow waters of Tasmania, and smaller than your hand. Usually a well hidden light brown, it shows off distinct bright blue rings all over its body when threatened. These rings are so bright that they are almost luminescent and often have red around the edges. This ink is our most saturated blue ink to date, with a magnificent red sheen on most paper types.
