It is also waterproof (depending on the surface), and the paint will stay bright and colourful for ages. It takes a lot of time to fade away.
If you paint on surfaces such as wood, plastic, canvas or paper, the ink will be permanent, whereas if you paint on surfaces such as glass or even a person's skin, the ink can be removed and you can recreate something new.
Posca pens come in different sizes, which is really great.
If you go out and buy some, here are a few tips about the sizes. The size they give are usually according to the size of the line it draws.
There are various tip sizes: The Ultrafine has a 0.7mm line and is perfect for outlines and details. The line it produces is the same as a ballpoint pen. The Fine draws a 1.3mm line, so a little bit bigger than the Ultrafine. The next size up is the Medium, which I think is the most popular pen for artists. It draws a 2.5mm line. This one is like a normal size marker, so it is good enough for details but also good for colouring and filling in big spaces.
Then comes the Medium Chisel, which are different from the first three pens as these pens have a chisel tip. A chisel tip is basically a big tip that can produce different thickness of lines when used at different angles. It has an 8mm tip, which means that the highest thickness it can draw will be an 8mm line.
Finally, the biggest Posca marker is the Broad Chisel, which also has a chisel tip, but the highest result will be a 15mm line.
All the pens need a good shake every time you use them, so the ink stays fresh and into the tip.
Posca is really generous on the amount of paint they put in each pen, so even though they can be a bit expensive in some places, they are really worth it.
A lot of artists are using them today and they can be used in a variety of ways. For example, you can use these markers for body art or to paint surfboards. You can do a lot of amazing things with these pens.
Uni Posca pens are also safe, odourless and non-toxic, which makes them ideal for kids too.
You can buy them online for much cheaper prices at Poscart or Artgear or you can also find them at news agencies, but there are less colours and sizes available at news agencies.
wow you say for Body art. BIG NO NO.
Yes they are non toxic and getting some on fingers will be okay but as a bodypainter, we have to have insurance and all sorts... these are NOT okay. Irritations can occur, they are NOT simple to remove. I wish they were useable as I LOVE posca markers but fact is, they are not.
Even their website does not recommend them for body art
