Uni Posca Paint Marker Review – Posca Vs Copic

Uni Posca Paint Marker Review

Art markers can be much easier to handle than regular paint and brush and have been quite popular with artists.

Lately a newly released type, the paint marker by Uni Posca, has been receiving a lot of attention.

In this Posca markers review article, I’ll try to go over everything you need to know to decide if these markers are the right fit for you.

The Basic Overview

  • Water-based
  • Max of 35 colors
  • Interchangable nibs
  • Nonrefillable
  • Permanent on porous surfaces

The Uni Posca paint pen is one of the many products besides pens, markers and brush pens that the Japanese company called Mitsubishi Uni makes. Although most of their products are only sold in Japan, the Uni Posca paint pen has become popular abroad as well.

What makes them unique compared to other art markers is that they use a water-based paint compared to the alcohol-based ink that most markers use. Therefore working with these markers gives a completely different experience. Some even mentioned that it feels like working with acrylics.

Different colors can easily be mixed together while the paint is still went, and the paint can be diluted with water if you want a lighter color.

However, the Uni Posca markers are permanent on porous surfaces so you will have to work fast. If you are using a non-porous surface, you can rewet or remove the paint with water.

A little minus is the fact that you can’t refill these markers. Once you are out of ink, you will have to buy a new one. I have seen some people mention online that they tried to refill them anyways but the results vary and the manufacturer doesn’t recommend it.

Additionally, there are only 35 different colors you can choose from which feels a little limited compared to other art markers. So you will either have to plan your work accordingly or learn how to blend like a pro.

Posca Pen Sizes and Nibs

You can buy the Uni Posca markers with the following 7 different nibs:

  • 0.7mm ultra-fine pin tip
  • 0.7mm extra-fine bullet tip
  • 0.9 – 1.3mm fine bullet tip
  • 1.8 – 2.5mm medium bullet tip
  • 8mm chisel tip
  • 15mm extra-broad tip
  • 1-10 mm a brush pen tip

As you can see, there are 5 different types of nibs (pin, bullet, chisel, broad, brush) and each nib has its own size ranging from 0.7 mm to 15 mm.

Depending on what you are working on you might want to use different nibs. For example, a chisel tip or broad tip would be ideal for calligraphy, while a pin or bullet tip could be used for detailed illustrations.

Fortunately, you can change the tips on your markers to suit the occasion. Since the markers only come with 1 nib, you will have to buy the others separately. But they aren’t very expensive.

How To Use Posca Pens

Working with these paint markers is similar to using other art markers. But before you using them you have to prepare them to make sure the paint is well mixed and flows smoothly.

  1. Shake the markers hard enough to hear a clicking sound
  2. Press the tip several times on a piece of paper to get the paint flowing
  3. Draw a test line to see if the paint comes out evenly
  4. If at any point while paint doesn’t come out freely, shake the marker again
  5. When you are finished you can clean the tip under tap water

Posca Pen Techniques

  1. Create a fading effect by applying water with a soaked brush before the paint dries
  2. Mix colors directly on your work surface to blur or blend
  3. Unlike most other markers you can layer lighter colors over dried dark colors
  4. Blow on the tip of the marker to make a spray effect similar to spray paints

What Surface Can I Use Posca Paint Markers On?

One of the main features of these markers is that you can use them on many surfaces besides just paper or canvas. Some materials you can work with are:

  • Paper
  • Stone
  • Ceramics
  • Glass
  • Fabric
  • Plastic
  • Metal
  • Wood

Are Posca Paint Markers Permanent?

As mentioned above, the these markers are only permanent on porous surfaces such as paper or plastic. On smooth surfaces like glass you can remove the paint with a damp cloth.

If you want to make the paint permanent on smooth surfaces like metal, stone or wood you can apply a layer of MSA varnish.

When working with ceramics or small glass items you can bake them to make the paint permanent. Whereas paint on fabric becomes permanent after you iron it.

Posca Vs Copic Markers

When it comes to alcohol-based markers, Copic has been on the top of the list for a long time. However, the Uni Posca markers use water-based paint, which makes them a completely different kind of marker.

I my opinion, I would recommend Copic markers if you are planning to work on paper or canvas. Not only are do they come in way more colors, you can also refill them which can save you money in the long run.

However, Uni Posca markers really shine when it comes to working on other surfaces, which makes them great for rock painting, glass painting, etc.

Where To Buy Uni Posca Markers?

Finding Uni Posca Markers in your local store might be a little tricky sometimes. That’s why I would recommend buying them directly from Amazon for convenience.

They normally come in a set of 7, 12, 15, 24 or 29 colors and you can choose which nib size you prefer. You can also buy colors individually but that normally will cost you more than buying the prepackaged set.

Other places you might also look at to find them are DickBlick, Ebay, Jetpens, and Marker Supply
