Posca markers are permanent markers and their ink is water-based, non-toxic, light-resistant and waterproof. 

Their colors are bright and opaque. They stick to all surfaces: paper, cardboard, wood, metal, porcelain, glass, fabric, rubber, latex, vinyl, etc. 

Instructions Shake the marker well with the cap closed until the ball clicks, remove the cap and press the tip several times on a test paper until the ink starts to flow into the tip. 

To make them permanently indelible, depending on the material, do the following: Paper/Cardboard: You don’t need to do anything, the Posca pigments will be absorbed by the paper fibers, making them permanently indelible.

Clay/Polymer Clay (Premo, Fimo, Cernit): Bake the objects in the kitchen oven for 20-25 minutes at 120-130ºC, then spray with a clear spray varnish. 

Fabric: For fabrics, iron the fabric inside out for 5 minutes (without steam) to make the item washable. The fabric can then be washed at up to 40°C.

Porcelain: For permanent fixation on mugs and cups, bake the items in the kitchen oven for 45 minutes at 160°C. The items can then be washed at up to 40°C. 

Metal: Spray with clear spray varnish. Glass: Bake the items in the kitchen oven for 45 minutes at 160°C, then spray with a clear spray varnish.

Wood: Spray with clear spray varnish. Plastic: Spray with clear spray varnish.

2. Press the tip several times on a scrap piece of paper until it is filled with color and the color you see on the paper is opaque and intense (not transparent). 
3. Cleaning the tip
If you need to clean the tip of the marker, this can be done with tap water or you can leave it in a container of water overnight until all the color is dissolved.
4. Placing the tip upside down
If the tip of the marker breaks, you can remove it and place it upside down.

If the tip dries out in case the cap was not closed properly, you can still place it in a container of water and use it again.
