To make permanent: Paper/Card: No action needed - POSCA pigment will be absorbed into the fibres, making it permanent.

The bullet shaped nib of 3M gives the user more line control, allowing them to utilise the thinner and thicker aspects of their nibs. Uni POSCA Markers contain water-based pigment inks that produce poster-like, vibrant colours. They are lightfast, waterproof, and will write on virtually any surface-from glass to paper-without bleed. Once dry, the opaque ink can be completely covered with a new ink application. We recommend giving these pens a try with black paper for an incredibly vibrant aesthetic, or with bristol board for exceptionally smooth flat application.
