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.
