These markers have a versatile fine fibre tip making them ideal for all types of art. Posca writes on virtually 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 easily removed from glass, making it ideal for temporary signs and window art. Once dry, you can easily layer over the top to build your design and correct any errors. Alcohol free, solvent free.
