If you have a question about the use of POSCA? If you want to try it on a new material? If you want to mix colours? Or if you need a tip to correct a mistake?

We have gathered some frequently asked questions about the use of POSCA.

How to store your makers?

POSCAs can be stored horizontally or vertically. However, it is preferable to store POSCA brush horizontally. The ball inside the barrel enables paint to flow at any time. The paint being perfectly preserved in the barrel.

What is the drying time?

The drying time is extremely quick. Generally, the paint dries quicker on porous surfaces than on smooth ones. In any case, wait a few minutes and the paint will be dry.

How to avoid bleeding?

The valve and piston mechanism prevents bleeding. To control the flow, press the tip down on scrap paper when priming POSCA.

Do I need some specific material to use POSCA?

You do not need material such as a brush, a cloth nor water: POSCAs enable you to paint neatly and accurately. You do not need any additional materials.

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.

Is POSCA refillable?

You cannot refill POSCA. Some users do reuse paint from one marker to another, in particular to mix colours. Mitsubishi Pencil Company has however not designed it for that use.

Another tip: See also "how to mix colours?".

Is Posca recommended for creative workshops with children?

POSCA stimulates children's creativity. With these fun and handy markers, they can finally play with paint without getting dirty. POSCA is often used in activity centres.

Another tip: There are plenty of games you can make using POSCAs and recycled items (yoghurt pots, terracotta pots, cardboard, wood...).

Is POSCA's paint permanent?

POSCAs are water-based pigment paint markers which can write on any surface. Paint is permanent on porous surfaces, and removable on non-porous surfaces such as glass.

Another tip: We have tested POSCA's resistance on more than fifty materials. For further information, click on "materials".

Why should I test POSCA before use?

Paint flow is controlled by a valve and a piston mechanism. To regulate and optimise the flow, try on a piece of paper before use.

Another tip: Keep the scrap paper in case you need to prime POSCA again.

What should I do to make the colour permanent?

POSCA's paint is permanent on porous surfaces. You can further optimize its adherence by following one of the next three steps: apply a varnish (see the workshop with salt dough magnets), bake in the oven (ceramic...) or iron (see the ecological bag workshop).

Another tip: For further information, see 'materials'.

What should I do when the tip has dried?

Don't panic 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.

Another tip: In case the tip is extremely dry, you can take it out simply by pulling and rinse it with water.

Are tips replaceable?

The tips of the following references can be replaced when dirty or worn: POSCA PC-1M, PC-3M, PC-5M, PC-8K and PC-17K.

Another tip: For the above references, tips are also reversible.

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.

Can I use POSCA as make-up?

POSCA can easily be cleaned off the skin and is non-toxic. However, it is not a cosmetic and has not been tested against cosmetic or dermatology standards. The manufacturer will therefore not be responsible for possible reactions on the skin if used incorrectly.

Another tip: The paint can easily be removed with soap and water if it comes into contact with skin.

Can children use POSCA?

POSCAs are water-based markers. They are odourless and totally safe for children to use. However, as they are quite technical, we recommend them for children over 5 years old.

Another tip: If you have lost the cap and the tip is dry, you can still soak the tip once again (See 'What should I do when the tip has dried?').

How to use POSCA brush?

Shake the marker vigorously with the cap securely attached in order to move the ball inside the barrel. To use the marker, remove the cap and the protection on the push button. Press and hold the push button to start the paint flowing. Replace the cap tight after use.

Another tip: You do not need to press the push button for too long and only once the cap has been removed.

Is POSCA toxic?

POSCA's paint is water-based, without solvent and odourless.
In fact, beekeepers use it to identify the queen in beehives! A colour corresponds to each year which enables them to determine the insect's age.
