If you’re searching for vibrant, versatile paint markers that thrive on rocks, wood, glass, canvas, plastic, fabric and more, you’ve landed in the right shed. These acrylic markers are the go-to choice for artists, students, muralists, and anyone who’s ever looked at a blank object and thought: yeah, I’m gonna draw on that.
Each pen is packed with highly pigmented, water-based paint that dries fast to a matte, waterproof film on porous surfaces and wipes off glass, metal, and plastic with an alcohol swab. They’re permanent where you want, erasable where you don’t, and come in every colour, size and finish you could dream of. From detailed journalling to giant murals, Posca’s ready to tag, sketch, letter, decorate, colour-in or create chaos wherever you point the nib.
We stock a wide range of Posca paint markers in Australia, dispatching them quickly from Melbourne and Brisbane, and packing orders with the speed and care of a caffeinated art enthusiast.
A Tagger’s Tool Turned Global Obsession
Born in Japan in 1983, Posca was originally designed as a non-toxic, high-pigment marker with paint-like coverage, and graffiti writers instantly clocked its potential. With no smell, no mess and insane opacity, it became the ultimate stealth tool: easy to control, hard to miss. By the ’90s, muralists, skaters, surfboard designers and street-art legends across Europe and Australia were slapping Posca onto walls, trains, wood, leather and concrete.
Tip from the Shed: Many OG street artists still sketch out their mural concepts with Posca before picking up a spray can, it’s like a battle plan in marker form.
Now? Poscas live in classrooms, tattoo studios, tote bags and toolbox drawers. Whether you're customising kicks, crafting café menus or drawing anime eyes in the margins of your science notes, this is the pen that does it all, loudly.
Why Posca Is So Damn Good
Posca markers aren’t just markers, they’re portable paint in a pen, built with real-world versatility. The ink is a water-based acrylic formula that’s rich, matte, lightfast, and layerable. It adheres permanently to porous materials and wipes off easily from non-porous ones. And because they’re xylene-free, low-odour, and EN 71-3 certified, they’re safe for classrooms, kitchens and kids’ craft corners.
Surfaces they love:
Timber, paper, canvas, clay, and rocks (just seal if it’s going outdoors)
Glass, ceramic, metal, and plastic (wipe-clean for temporary signage)
Fabric (heat-set to make it laundry-safe)
Value perks you’ll love:
Reversible or replaceable nibs on most sizes
A single PC-5M can draw up to 500m of line
Shelf life = years, as long as you cap 'em tight
Compatible across finishes (pastels + metallics + glitters = no problem)

Tips from the Shed
Store horizontally, not nib-down.
Don’t over-pump; flooded nibs are a pain.
Want even more control? Sketch in pencil underneath, then trace.
On slick surfaces, clean with alcohol before drawing and seal if needed.

Posca FAQs With Art Shed
How do you prime a Posca pen?
Shake vigorously, then pump the nib vertically on scrap until ink saturates.
Are Posca pens waterproof on rocks?
Yes—once dry, they’re water-resistant; seal with acrylic varnish for outdoor use.
What’s the difference between PC-1MR, PC-3M and PC-5M?
PC-1MR 0.7 mm ultra-fine; PC-3M 0.9–1.3 mm fine bullet; PC-5M 1.8–2.5 mm medium.
Do Posca pens bleed on fabric?
No—on pre-washed cotton, they sit on the fibre; heat-set for laundry-safe art.
Are Posca pens non-toxic?
Yes, they’re water-based, xylene-free and EN 71-3 certified child-safe.
Do Posca markers wash out of clothes?
If not heat-set, pigment can often be removed with warm water and detergent. Act fast for best results.
Are Posca markers permanent on clothes?
They become reasonably permanent when left to dry 24 hours, then heat-set for 5 minutes (medium iron, cloth barrier, no steam). Colours survive cold washes—avoid hot tumble-drying.
What not to do with Posca markers?
Don’t press the nib non-stop—floods the ink. Don’t store nib-down. Don’t add liquid to the barrel. Don’t leave the cap off—they dry fast.
How long do Posca pens last?
A PC-5M lays down around 300–500m of line. Cap them tightly and they’ll last for years. Swap or flip nibs when they fray.
Are Posca markers waterproof on glass?
Yes—after curing, they resist smudges. But they’re removable with alcohol or cleaner, so seal with varnish for permanence.
