ProMarker Markers feature a double-tip design to meet all your creative project needs: a flexible tip for detail work and a wide chisel tip for colouring larger areas. The permanent alcohol-based ink is non-toxic, easy to mix and covers surfaces evenly. The markers can also be used on ink-resistant surfaces such as acetate, glass, plastic and wood. Contains 24 x Promarkers Markers: Yellow, Amber, Sunflower, Mandarin, Cocktail Pink, Antique Pink, Berry Red, Burgundy, Maroon, Carmine, Amethyst, Mulberry, Plum, Indigo Blue, Royal Blue, Azure, Denim Blue, Turquoise, Lush Green, Mint Green, Bright Green, Lime Green, Pear Green and Khaki.
