Short answer
ONE4ALL is a refillable, pump-action acrylic marker in line widths from about 1 to 15 mm. It was above average on every test in the largest independent comparison, with one weakness: it lifted dried paint when layered over other media. It costs more per pen than Posca; refills make that back only if you use a lot of a few colors.

How it performed
In Sarah Renae Clark’s pump-action comparison, ONE4ALL was “better than most of the valve-action markers” tested and above average on every test. The one weak spot was layering over other media: on one test it pulled up the dried paint underneath and absorbed ballpoint ink from a lower layer. In practice that means letting earlier layers cure fully and not scrubbing over them.
“They were above average on all my tests, only lacking in their ability to layer on other media.”

Which ONE4ALL size to buy
| Line width | Good for | Shop |
|---|---|---|
| 1 to 2 mm | Outlines, lettering, detail | Search 2 mm |
| 4 mm | The everyday size: fills and bold lines | Search 4 mm |
| 8 mm | Large shapes, block letters | Search 8 mm |
| 15 mm | Backgrounds, murals, canvas fields | Search 15 mm |
If you are starting from zero, a 2 mm set for detail plus one or two 4 mm pens in your most-used colors covers most work. See the tip size chart to compare widths.
Is the refill system worth it?
It depends on how you paint. Refills pay off when you empty pens: murals, big canvases, signage, or a style built on a few colors. If you use thirty colors a little each, you may never empty a pen, and a cheaper non-refillable set is the better buy. Refills also let you mix your own shades in an empty marker, which Molotow encourages.
ONE4ALL vs the alternatives
- Posca: cheaper per pen, wider range including brush tips, top score in the same review, but not refillable. Full comparison: Posca vs Molotow.
- Montana Acrylic: also refillable, with even bigger tips (30 and 50 mm) and a matte finish the maker calls weatherproof when dry (maker sheet).
- Pilot Pintor: a close second to Posca in the independent review, at a mid price.

Using ONE4ALL well
- Shake until the ball rattles freely, then prime on scrap. Pen not flowing?
- Let layers dry fully before drawing over them, given the lifting seen in the independent review.
- Outdoors, finish with a clear coat suited to the surface. See how to seal acrylic marker art.
Questions people ask
Is Molotow ONE4ALL refillable?
Yes. Molotow sells ONE4ALL refill bottles and empty markers, and promotes mixing custom colors. Posca, by contrast, is not refillable.
What sizes does Molotow ONE4ALL come in?
Molotow’s shop lists ONE4ALL line widths from 1 to 2 mm up through 2, 4, 5, 6, 7 and 8 mm to a wide 15 mm, including twin-tip models.
Is Molotow ONE4ALL waterproof?
Acrylic paint is permanent once dry on porous surfaces, but that is not the same as weatherproof. For outdoor pieces, finish with a clear coat suited to the surface.
How do I start a Molotow marker?
Shake it well with the cap on until the mixing ball moves freely, then press the tip on scrap paper a few times until paint flows. Do not over-pump; it floods the tip.
Can I use acrylic markers on canvas?
Yes. Molotow ONE4ALL and other acrylic markers work on primed canvas. Wide ONE4ALL tips (4 to 15 mm) block in color quickly, the 1 to 2 mm tips handle edges, and a spray varnish protects the finished piece. Let each layer dry before the next.
What are some good acrylic markers for canvas?
Wide, pump-action markers do the most work on canvas: Molotow ONE4ALL 4 to 8 mm and 15 mm, Posca PC-8K and PC-17K, and Montana Acrylic 15 mm. Pair one wide marker with a medium tip around 2 mm for outlines and details.
What is the best acrylic marker in the world?
There is no single best. In the largest independent comparison we found, Posca scored highest overall among pump-action markers, Pilot Pintor came close, and Molotow ONE4ALL was above average on every trial. Molotow wins if you want refills and very wide tips.
Do acrylic markers work the same as acrylic paint?
Not quite. Marker paint is thinner so it can flow through a nib, which suits lines, lettering and flat color but makes big areas and blending slower. Molotow says ONE4ALL paint can be diluted with water and mixed, so artists often combine markers and brushed paint.
Are acrylic paint markers good for paint by numbers?
They can be, for small shapes and clean edges: a 1 to 2 mm tip fills numbered areas without a brush. Cover light printed numbers with opaque colors, and use a wider tip or brushed paint for the largest areas, which streak less.
