The STABILO woody 3-in-1 is a unique multi-talent colouring pencil, watercolour, and wax crayon in one. It offers 8 times more colour than a traditional coloured pencil with extra colour intensity, even on the darkest of papers. Its chunky shape, size, and indestructible lead make it perfect for children's hands, promoting a good grip. This versatile pencil can be used on various smooth surfaces like glass, plastic, and leather, and the colours can be easily wiped off glass with water. It's also effective on dark surfaces, cardboard, paper, wood, and ceramics. You can heat the tip for a waxy oil texture for colouring and painting, or dip the pencil in water for lovely watercolour effects. Colours can be blended and layered for magical multi-dimensional effects. This classpack includes 30 pencils in 10 assorted colours and 2 woody sharpeners. The thick lead provides extra long colouring fun and is non-breakable, even for adventurous children. Hobby artists will also enjoy the many ways this multi-talented pencil can be used.
