Uni POSCA PC-8K Instructions & Frequently Asked Questions
How to Prime Posca?
Shake the marker vigorously with the cap securely attached in order to move the ball inside the barrel. On a test sheet, press the tip down several times to start the paint flowing. Replace the cap tightly after use.
Should I Test POSCA Before Use?
Paint flow is controlled by a valve and a piston mechanism. To regulate and optimize the flow, try on a piece of paper before use. Another tip: Keep the scrap paper in case you need to prime PO SCA again.
Can Children Use POSCA?
PO SCAs are water-based markers. They are odourless and totally safe for children to use. However, as they are quite technical, Uni-Ball recommends them for children over 5 years old.
Can I Use POSCA AS Make UP?
POSCA is designed as an arts & crafts marker, it can easily be cleaned off the skin and is non-toxic. However, it is not a cosmetic and has not been tested against cosmetics or dermatology standards. The manufacturer is quite clear that they will therefore not be responsible for possible reactions on the skin if used incorrectly.
What is the Drying Time?
The drying time is extremely quick. Generally, the paint dries quicker on porous surfacesthan on smooth ones. In any case, wait a few minutes and the paint will be dry.
What Should I do When the Tip Has Dried?
if you have lost the cap and the tip has completely dried, thanks to the piston and valve mechanism, you can flow paint once again by priming the POSCA marker again.
How to Correct a Mistake?
If you have missed a line or got the wrong colour: overlay! With POSCA, you can overlay colours as many times as you wish. Another tip: Wait until the first layer has dried before applying another one.

If you try to use these pens on a very absorbent surface they may not perform as well as on a less absorbent and smooth one. The nib is chisel in shape and can deliver a 4mm to 8mm line. It really is like painting with a brush but without the flex of the bristles. 16-Apr-2016 Product:

Almost behaves more like a chalk marker than a paint marker; very easy to run off marks even when completely dry. Stick to Edding pens 21-Jul-2015 Product:
