Uni-Ball POSCA PC-3M Paint Markers, Reversible Fine Tip — Assorted 8-Pack, Opaque Matte

Uni-Ball POSCA PC-3M markers are water-based, reversible fine-tip paint pens that lay down opaque, matte colour on almost any surface.

These POSCA PC-3M markers deliver vivid, professional-looking pigment in a compact, comfortable barrel. The water-based formula is odourless and quick-drying, so you can layer and blend colours while preserving a clean workspace. A mixing ball inside each marker keeps the paint consistent, and the valve mechanism maintains steady flow and seals the tip to prevent drying between uses.

How do these markers perform on different materials?

POSCA PC-3M pens were designed to work reliably across a wide range of surfaces — from paper and wood to metal, glass, plastic and textiles. The opaque, matte finish covers dark backgrounds well, and once dry the paint resists light weathering. Because the ink is water-based, it can be reactivated when wet for blending, but becomes stable and durable after drying.

• Works on paper, canvas, wood, ceramic, glass, metal, plastic and stone
• Opaque pigment covers dark and light surfaces equally
• Quick-drying yet layerable for gradients or corrections
• Weather-resistant surface after curing

What makes the reversible fine tip useful for artists and crafters?

The PC-3M reversible fine bullet tip offers precision for detailed work while also allowing slightly broader strokes when flipped. Its shape gives consistent lines and smooth ink flow, which helps for lettering, outlining, and small fills. The ergonomic barrel and secure cap make prolonged sessions easier and keep the tip protected between uses.

• Reversible fine point for both detail and modest coverage
• Steady flow thanks to the internal valve mechanism
• Comfortable barrel for controlled strokes and less hand fatigue
• Sealed cap extends marker life and prevents drying out

How should I prime and maintain these paint markers?

Priming is simple: shake the marker with the cap on to mix pigments, then press the tip down on scrap paper until colour flows. The internal mixing ball and valve system ensure even consistency through the life of the pen. Store markers horizontally with caps on to preserve the tip and pigment balance.

• Shake well with cap on to mix pigments before first use
• Prime by pressing tip gently on scrap until ink saturates
• Use on dry, clean surfaces for best adhesion and finish
• Store horizontally and recap after each session to protect tips

Who this is for: Creators, hobbyists, artisans, teachers and decorators who want a portable, dependable paint marker for precise colour work. The Uni-Ball POSCA PC-3M pack of 8 assorted colours suits people who need fast-drying, odourless pigment that performs on many substrates — from classroom projects and signage to mixed-media art and custom detailing.
