Uni Paint Marker PX-21 | 0.8-1.2mm | Red | Pack of 1 - Metal & Glass Marking

Mark metal, glass, plastic or wood and have the mark stay there. The Uni PAINT PX-21 carries opaque oil based paint through a fine bullet acrylic nib at 0.8 to 1.2 mm and dries glossy, so red reads clearly on shiny and dark surfaces where ordinary ink slides off. Best for bold accents, festive detail and strong headline lettering.

Specifications

Before You Buy

• Oil based paint carries a solvent smell while wet, so work in a ventilated space.
• The maker's pack panel states the dried paint is waterproof, fade resistant and heat resistant.
• Marks on non porous surfaces are meant to stay, so test a hidden corner first if the surface matters.
• One marker, one colour. This pack contains a single red marker, not a set.
• We state no toxicity, skin or food contact rating for this marker; read the maker's own pack information if that matters for your use.

Ideal For

• Marking metal, glass, plastic and rubber
• Workshop, garage and industrial labelling
• Keychain, coaster and hard surface craft
• Outdoor pieces that must survive weather

Perfect for

• Labelling tools, tins, cables and storage boxes

Compatibility

Works with: metal, glass, plastic, wood, rubber, stone, concrete, ceramic and paper.

Pairs well with: MDF and wooden bases, keychain blanks and painted craft surfaces.

Not suitable for: everyday writing in notebooks, and any piece where you may want the mark removed later, since the paint is made to stay.

How to Use

1. Shake the marker firmly with the cap on.
2. Press the nib down on scrap card several times until the paint fills the tip and the line runs clear.
3. Clean and dry the surface, then mark in one steady stroke.
4. Let the paint dry fully before you handle or stack the piece.
5. Recap tightly straight after use, since oil based paint dries out in an open tip.

Frequently Asked Questions

How wide a line does the Uni PAINT PX-21 draw?
It lays a 0.8 to 1.2 mm line from a fine bullet tip, in a single red shade.

How is the PX-21 different from the PX-20?
The PX-21 is the fine nib at 0.8 to 1.2 mm, made for small writing and close detail. The PX-20 is the medium nib at 2.2 to 2.8 mm and covers more ground per stroke.

Will it write on metal, glass and plastic?
Yes. Oil based paint bonds to clean non porous surfaces including metal, glass, plastic, rubber and stone, and it also works on wood and paper. Wipe the surface clean and dry before you mark it.

What surfaces does red look best on?
It reads strongest over pale and mid tone bases such as white canvas, light wood and cream card. Over a very dark surface, lay a lighter base colour first or give it a second pass once the first coat has dried.
