Posca Pens

At Oxlades, we proudly stock a wide range of markers and paint markers including the extremely popular Posca painting pens. These pens are ideal for school, personal, or commercial art and painting projects and can elevate any project.

What are Posca Pens?

They are acrylic or water-based paint markers that you can use for various creative projects. The paint is non-toxic, lightfast, opaque, and water-resistant when it’s dry. It also does not bleed through paper like felt-tip marker ink does.

Unlike other pens, Posca markers are not oil or alcohol-based. This means while the paint is waterproof and permanent when it has dried on your surface, it will still come off hands and clothes when washed with detergent.

The acrylic is easy to blend when wet but dries quickly enough for convenient paint layering. The paint offers a good level of density and surface coverage.

It can be used on most surfaces. It’s suitable for wood, glass, paper, cardboard, and even metal.

What Can I Do with Posca Pens?

Posca markers are extremely versatile. You can use them on most surfaces for most kinds of projects. However, they’re extremely well suited to detailed work. As the pen design allows you a large amount of application control, they are great for fine lines and small details.

This design also makes them ideal for posters and other projects where you want to include writing. The marks made by these pens are also conveniently consistent - they’re much easier to use than paint brushes.

If you have a professional, amateur, school, or personal project to do, these pens won't let you down. Check out our range our website to shop for these handy art supplies today!

FAQ's

What is special about Posca pens?

Posca pens are beloved by artists, hobbyists, designers, and educators around the world for their vibrant colours, smooth application, and exceptional versatility. What makes them truly special is their unique water-based pigment ink that works beautifully on almost any surface (paper, canvas, wood, fabric, plastic, metal, glass, ceramics, and more) without bleeding, seeping through, or requiring any preparation. These pens deliver bold, opaque coverage, making them ideal for layering, highlighting, and adding crisp details to any project. At Oxlades Art Supplies, we stock a wide range of Posca pen sizes and colour sets, so you can find the perfect tools for everything from fine line work to large-scale murals. Artists love them for their control and convenience, while crafters and DIY enthusiasts appreciate their mess-free, no-fuss format. Posca pens are more than markers, they're a gateway to unlimited creative possibilities.

Are Posca pens waterproof?

Yes, once dry, Posca pens are waterproof and permanent on most surfaces, making them an excellent choice for artwork that needs to last. The water-based pigment ink becomes highly resistant to water when applied to porous surfaces like paper or wood. On non-porous surfaces such as glass, metal, or plastic, the ink can be made more permanent by sealing it with a clear varnish or fixative. That’s why Posca pens are often used for outdoor signage, surfboards, shoes, plant pots, and all kinds of mixed media projects.

How long do Posca pens last?

Posca pens are built to last. The lifespan of a pen depends on how frequently it’s used and the size of the nib, but in general, a single pen can cover a surprisingly large surface area thanks to its high pigment load and controlled ink flow. Because they’re refillable and feature reversible tips, you can extend the life of your pens with proper care.
