Short answer
For marks that last on hard plastic, use an oil-based paint marker such as Uni Paint PX-20 or Sharpie oil-based: the solvent helps the paint bond to clean, slick surfaces. For craft and decor, water-based acrylic paint pens work but can scratch off, so seal them. Clean with rubbing alcohol first and lightly scuff glossy plastic. For labels, a permanent marker is fine.

Best paint pens for plastic: oil-based
Oil-based paint markers are the go-to for plastic that gets handled or goes outside. The Uni Paint PX-20 listing describes opaque, glossy marks on metal, glass, wood, rubber, concrete and plastic, fast-drying oil-based paint that withstands weather, heat and abrasion, and a solvent that lets the paint bond to clean surfaces. It also suggests lighter colors for dark surfaces and darker colors for light ones. Sharpie oil-based paint markers are the other common choice, in extra fine, fine and medium points. Brand details: Uni Paint markers and Sharpie oil-based paint markers.
Use oil-based pens in a ventilated room: they give off solvent fumes as they dry. The full category is on oil based paint markers.
Acrylic paint markers for plastic crafts
Water-based acrylic pens are easier to use and clean, with more colors, which makes them popular for decorating toys, planters and phone cases. The trade-off is grip: on slick plastic, dry acrylic can be scratched off with a fingernail. Posca says its paint is permanent on porous surfaces and erasable on smooth surfaces, and that work can be secured with a water-based spray varnish (Posca FAQ). Spray the first clear coat, since a brush can drag marker paint.
Permanent marker for plastic
For writing names and labels, a classic permanent marker is enough on most hard plastic. It is translucent dye ink, so it disappears on dark plastic, and rubbing alcohol can lift it from slick surfaces, which is useful for mistakes and a weakness for labels that get wiped. For a label that must survive, use an oil-based paint marker. If you need to take marker off plastic, see removing permanent marker from plastic and wood.
How to prep plastic for paint pens
- Clean
Wash with soapy water, rinse and dry, then wipe the area with rubbing alcohol to remove grease and mold release. Do not touch it again with bare fingers.
- Scuff glossy plastic
Lightly rub very shiny plastic with fine sandpaper or a scouring pad so the paint has some tooth. Wipe off the dust.
- Test a hidden spot
Try the pen on the underside. Let it dry, then scratch it gently with a fingernail. If it lifts, prime or switch pens.
- Draw and cure
Shake the marker, prime the tip on scrap, then draw. Let it dry fully before handling; oil-based paint takes longer to harden.
- Seal
For handled items, spray a light clear coat over the dry design.
Plastics that resist paint
Some plastics are hard to mark for good. Soft, flexible, slightly waxy plastics, such as many food containers, squeeze bottles and outdoor furniture, resist both ink and paint. The recycling code on the item can hint at the type. For these, a spray paint made for plastic is the better route: Krylon says its Fusion All-In-One spray offers reliable adhesion to plastic, metal and laminate with no sanding or priming needed (Krylon). Clean the surface first regardless.
Where to buy paint pens for plastic

Questions people ask
Do paint pens work on plastic?
Yes, on most hard plastics, if the surface is clean. Oil-based paint markers grip best: the Uni Paint listing says its paint contains a solvent that lets it bond to clean surfaces and names plastic among them. Water-based acrylic paint pens write on plastic too, but on slick plastic they can scratch or peel off unless sealed. Soft, waxy plastics resist both.
Does Home Depot carry paint pens?
Yes. The Home Depot sells paint pens online, including Sharpie paint markers, and hardware stores mostly stock oil-based markers for marking and labeling. In-store stock varies, so check the store’s website. Water-based acrylic art paint pens are easier to find at craft stores and online.
What kind of paint will stick to plastic?
Paints formulated for plastic, such as spray paints sold for plastic. Krylon says its Fusion All-In-One spray offers reliable adhesion to plastic, metal and laminate, with no sanding or priming needed. Otherwise, use a plastic primer under ordinary paint. For small marks and designs, oil-based paint markers stick better than water-based ones.
Are acrylic markers permanent?
On porous surfaces such as paper, wood, canvas and stone, they are effectively permanent once dry. On non-porous surfaces such as plastic, glass and glazed ceramic, they are not: dry acrylic paint can be scratched or washed off. Posca, for example, describes its paint as permanent on porous surfaces and erasable on smooth surfaces. Seal acrylic work on plastic to protect it.
What paint sticks to plastic permanently?
No paint is truly permanent on every plastic, but a plastic-bonding spray paint or a plastic primer under paint gives the most durable finish, and oil-based paint markers are the most durable pens. Clean with rubbing alcohol, scuff glossy areas lightly, let the paint cure fully, and add a clear coat on items that get handled.
