What Are Posca Pens?
Posca Pens are water-based paint markers made by Uni Mitsubishi Pencil. Unlike regular felt-tip pens, Posca Pens contain opaque, highly pigmented ink that works on almost any surface. You can use them on:
- Paper
- Canvas
- Wood
- Glass
- Metal
- Stone
- Plastic
- Fabric
Because they’re so versatile, they’ve become a favourite tool for artists, crafters, illustrators, and even teachers.
Why Are Posca Pens So Popular?
1. Bright, Bold Colours
One of the main reasons people love Posca Pens is their stunning colour quality. The ink is smooth, rich, and stands out on both light and dark surfaces. This makes them perfect for posters, canvas art, doodles, and craft projects.
2. Easy to Use
Posca Pens work just like a normal marker, but they produce paint-like results. You don’t need brushes, water, or a palette. Simply shake, press the tip to prime the ink, and you’re ready to draw.
3. Non-Toxic and Safe for All Ages
Because they’re water-based and odourless, Posca Pens are safe for children, students, and adults. You don’t get the harsh smell common with many paint markers.
4. Can Be Layered and Blended
You can layer colours on top of each other without smudging once the bottom layer dries. You can also blend shades together while they’re still wet to create gradients or smooth transitions.
5. Long-Lasting and Refillable Tips
Many Posca Pens come with reversible or replaceable tips, making them last much longer than standard markers.
Different Types of Posca Pen Tips
To help you create different effects, Posca Pens come in a range of tip sizes. Cowling & Wilcox usually stocks the full range, including:
- Extra Fine (PC-1MR): Best for detailed drawings, outlines, and small lettering.
- Fine (PC-3M): Great for illustrations, journaling, and neat writing.

- Broad (PC-7M & PC-8K): Perfect for large surfaces, posters, bold signs, and big art projects.
