Posca acrylic paint markers have become quite popular in recent years. Made by Uni/Uni-ball (Mitsubishi Pencil Co.) of Japan, these markers are very high quality. The colors are bright, they flow beautifully and apply evenly, can be used on nearly any surface, dry quickly, and can be layered or blended. I absolutely L O V E these markers!

Buying Posca markers online can get really confusing, with conflicting information about what colors are available in which sizes (even between official sites,, and, what colors come in which packs, and inconsistant color names in product listings; so I've made a handy guide!

Guide is incomplete and still in progress, if you have something to add please leave a message on Neocities or #Fuzz3676 on Discord. I'll probably be adding photos to this page later.

My Experience:

I originally purchased a set of 16 markers in PC-3M, immediately fell in love, and went to track down every color I could. I really had to work hard to track down all the colors in the cheapest possible way, since there is No existing set that contains all available colors, and the bigger sets tend to be pricey.

In addition to the full range of PC-3M, I have one PC-1M in White. I'm looking to add more 1M and 5M markers to my collection soon. I have noticed that my 1M White requires A LOT of shaking, I'm not sure if that is normal for this size.

I have only ever had 1 marker that didn't work. The Blue from my first pack worked fine at first, but quickly began to swing wildly between having a dry, scratchy tip, and then gushing everywhere if I tried to pump it even once. I bought some replacement tips thinking that was the problem, but it didn't help. I have noticed that a few of my markers have evidence of having leaked a little from the bottom, but it's dried and hasn't reoccured.

Overall, I'm really surprised at the amount of ink in these, I thought for sure my most-used markers would have dried up by now, but they continue to work flawlessly.

Where to Buy:

Always check your local craft supply or hobby shop first! You should be able to find them at most major craft store chains too.

Color Names:

The official English names for some colors appear to have changed. Also, some online listings use their own translation of the Japanese names, further adding to the confusion.

I'm not sure if any of these changes have been reflected on the markers themselves, but these are the colors that have changed on

Bright Yellow・やまぶきis nowOrange
Orange・だいだいis nowDark Orange
Blue・あおいis nowDark Blue
Green・みどりis nowDark Green
Red Wineis nowBordeaux
Aqua Green・パステルグリーンis nowSea Green

Because "Orange" refers to two different colors, the previously #3 Bright Yellow/やまぶき and what is now called #4 Dark Orange/だいだい. Luckily, these are very similar colors, but if you Need a match I'd suggest ordering more than one or buying in-person if you can.

Red is not a true firetruck red, but rather more of a red-orange.

They appear to have started calling the Fluorescent line "Fluo" for short.

Unavailable Colors:

It appears Turquoise (only PC-8K) might be discontinued.

Charcoal Grey is listed on, but not available in any size.

Metallic & Glitter:

Metallic and Glitter markers are different, and the Glitter markers are sometimes listed as metallic.

The Metallics are true metallics, with a flat shine.

The Glitter (ラメ入り) markers are more metallic than glitter, but have a slightly brighter shine with a light texture to it. The colors are fairly unsaturated and dark when out of the light, but when the light hits them they are very bright. They need to be shaken a bit more than the other markers, but make a neat transparent color with a slight sparkle when not shaken well. The Glitter markers also do not work as well over dark colors.
The Japanese Glitter set doesn't include Yellow and I had to order it seperately.

Silver is almost an exact match, ever so slightly darker, to Grey when the light isn't hitting it. They work very nicely together.

Glitter Yellow is signifigantly darker than Yellow out of the light, but lighter and brighter when in the light. Personally I don't like using them side-by-side.

When comparing Glitter Yellow to Gold, out of the light they are similar, Gold being a little darker, but in the light the difference is clear, with Glitter Yellow being much brighter and very saturated, the Gold almost looking bronze in comparison.

Glitter Orange is a little darker and more saturated than Bronze, of the two Glitter Orange is closer to Brown. In the light especially, they are very similar.

Skin Tones:

Unfortunately, Posca is severely lacking in browns and tans, which can make skin tones difficult. You may have to get creative. If you're having trouble, these colors work nicely:

Ivory:is a little yellow and very light, works for the extremely pale
Beige:is beige
Apricot:a little darker than Beige and less saturated than Light Orange
Light Orange:a little bright, but works nicely as a flesh tone
Light Pink:is light pink
Coral:works as a medium/dark with certain pallets
Brown:great color for medium-dark skin
Red Wine:is very desaturated, more a brown than a red. Darker than Brown
Cacao Brown:Darker than Brown, lighter than Dark Brown. PC-5M only.
Dark Brown:is REALLY dark, almost imperceptable from Black

Usage Tips

First and foremost, the number one reason I see bad reviews for these markers is because they didn't read the directions. These markers need to be primed before they can be used. Just shake it for a minute or so and then pump the tip down on a piece of paper a few times. You should be able to see the paint start to make it's way down the tip. Some inks flow faster than others. If you pump one too many times and you end up with a little puddle, just wipe the tip with a tissue and you should be good to go.

Shake before each use. Sometimes after sitting unused for a long time the tips dry a bit, a single pump or a dip in some water will get it going again.

I reccomend having a piece of scrap paper nearby when working with these, to prime tips, test colors, clean tips that have picked up other colors, and troubleshoot if need be.

The tips are washable and replacable, and for PC-3M and PC-5M the tips can be reversed as well. PCF-350 and PC-1MR have non-removable tips.

Generally, treat these markers like you would acrylic paint. You'll want to avoid using light colors on top of dark colors and work background to foreground. If you use lineart in your work, do the lines last.

Work in closely placed stokes; going back and forth over the same area or working in a circular motion will cause it to become gummy and clumpy. This is especially important if working on paper surfaces. If you miss a spot, wait for the paint to dry and come back to it later. This method will give you the most even coverage.

If you do notice clumps or bumps in the paint, wait until it has dried and scrape them off gently; reapply color if needed. This can happen even with normal use.

Apparently, Poscas can be blended if you work quickly and/or wet them. I haven't tried this. The tips are washable and replacable if, like me, you worry about keeping them clean.


Make sure the previous layer is fully dried and work quickly with confident strokes, it's possible to re-wet the layer beneath and it will become gummy or start to smear or blend.

Yellow is the weakest marker for layering, I've had the most luck laying down a layer of White before laying Yellow if I need to work on top of other colors. This goes for other light colors like Ivory or Beige as well, and works much better than two layers of the same color.

Mixed Media:

Ink works very well with these, both under and over the markers. I've used Copic liners over the top which applied very smoothly, dried quickly, and did not smudge.

They work great over colored pencils.

Custom Colors:

I haven't tried it, but I hear it's possible to mix cutom colors by removing the tips and carefully pouring the ink into an empty or low marker and giving it a thorough shake.

Canvas & Paper:

While Poscas can be used on nearly anything, THIS SITE has a really good breakdown of what types of paper Poscas play best with. But any thick, smooth paper will do great.

I've also used these on wood, plastic, and rocks. All of them were very easy to work on.

I've used these on skin for cosplay stuff and they are better than makeup or temporary tattoos. It doesn't smudge or wear off easily, but can be removed easily with just water and a light scrub. Obviously don't use these around your eyes or mouth.


The markers are plastic, acrylic paint is plastic, they aren't refillable and aren't recyclable.
Mitsubishi Pencil claims that PC-5M, PC-7M, and PC-8K markers are made using recycled materials.

Packaging for packs is usually plastic, although some are recycled paper with a plastic film.
Individual markers come wrapped in plastic film, sometimes even if included in a set.

The markers can potentially have their lives extended by adding water to the ink.
The empty markers can be cleaned and filled with ink from other markers or other materials.
The tips and ink pads can also be removed and cleaned for reuse with other markers.

DIY recylers may be able to make use of the material, I suspect they are PET #2, but use caution.
