The POSCA PC-3M has water-based pigments which can be blended when wet or overlaid when dry. The non-toxic ink produces opaque results that won't fade over time and the fine bullet tip lets you draw lines that can be read from a distance. These markers can be used on a variety of surfaces such as glass, metal, wood, cardboard, and paper. The POSCA PC-3M is permanent on porous surfaces and erasable on most smooth non-porous materials (creations can be protected with a fixative varnish). The stable pigments and strong UV resistance make this pen suitable for both indoor and outdoor use and the range of bright opaque colours provide strong coverage. The universal bullet tip of the PC-3M adapts to all types of creation and can be used to customise, create, decorate, or mark anything that inspires you with a precise and steady line. With the comfortable, round barrel, the POSCA PC-3M is easy to use for long periods. This marker has a fine bullet tip that measures 1.3 mm. This POSCA marker is apple green.
