Posca PC-8K - These markers have a large chisel shaped fibre tip, which can be used for filling in background colours or working on large-scale art such as wall murals or urban art. Posca writes virtually on any surface, metal, wood, canvas, plastic, fabric etc. and will not ‘bleed through' paper. Posca markers use water-based pigment ink to produce poster-paint-like vibrant colours. Posca is designed for temporary signs and window art as it can be easily removed from glass. Once dry, you can easily layer over the top to build your design and correct any errors.
