The acrylic markers buying guide
Most people should start with a medium, water-based pigment marker with a pump valve, the Posca PC-5M kind. Switch to an oil-based paint marker for glass, metal and slick plastic, and seal anything that lives outdoors.

Paint a pumpkin that outlasts a carved one
Skip the knife. Paint pens on an uncarved pumpkin give you crisp patterns and a pumpkin that keeps far longer. Base coats, the best tips for curves, and the sealer step.
The short version
Three rules cover most of what people get wrong with paint markers.
Start with water-based pigment
Pump-action markers such as Posca and Pilot Pintor handle rock, wood, canvas, paper and pumpkins. A medium tip around 1.8 to 2.5 mm is the one to buy first; add an extra fine 0.7 mm for outlines. Best markers for artists.
Match the paint to the surface
Glass, metal and slick plastic hold oil-based paint markers better. Anything headed for the dishwasher needs a bake-on glass and porcelain pen used exactly as its maker says. Acrylic vs oil-based.
Prime, layer, then seal
Shake with the cap on, press the tip on scrap until paint flows, let each layer dry before the next, and spray-seal anything that lives outside or gets handled. How to seal marker art.
Which marker for which surface
The surface decides the paint, the job decides the tip. Specs come from maker pages; finishing advice is general guidance, so test a hidden spot first.
Surface by marker type and tip size
| Surface | Best marker type | Tip size | Prep | Finish | Guide |
|---|---|---|---|---|---|
| Rocks and pebbles | Water-based pigment, pump-action | Fine 0.7 to 1.3 mm for detail, medium 1.8 to 2.5 mm for fills | Wash, dry fully, base coat if dark | Spray varnish, more coats for outdoors | Read the guide |

Questions people ask
Are acrylic markers permanent?
On porous surfaces such as wood, paper, rock and fabric, water-based pigment markers are permanent once dry; Posca says no fixative is needed on those. On slick surfaces like glass they can wipe off, and nothing is fully weatherproof without a sealer, so seal outdoor and handled pieces.
What is the difference between acrylic markers and paint pens?
Paint pen is the umbrella term. Acrylic markers are paint pens filled with water-based acrylic or pigment paint. Other paint pens use oil-based or enamel paint, which grips glass, metal and plastic better but smells stronger and is harder to layer.
Are Posca markers acrylic?
Posca describes its ink as water-based and pigment-based. It behaves like an acrylic marker (opaque, layerable, permanent on porous surfaces once dry), which is why nearly every buying guide, ours included, groups it with acrylic markers.
How do I start a fresh acrylic marker?
Shake it with the cap on until the mixing ball rattles freely, then press the tip down on scrap paper several times until paint soaks through. Do not pump hard and fast: that floods the tip and causes blobs.
Are acrylic markers safe for kids?
Look for the ACMI AP seal on the pack. A line that only says it conforms to ASTM D-4236 means it was reviewed by a toxicologist and labeled to match, which is not the same thing as non-toxic. Small caps are a choking hazard for young children.
Do acrylic markers work on fabric?
Some do. Posca says its markers suit fabric if you iron the design inside out with no steam and wash it inside out at a low temperature. Dedicated fabric markers stay softer on the cloth.
