Silk Crayons - a fun set of eight (8) vibrant colouring-in tools for kids. Silk Crayons will make you re-think your definition of a crayon… is it a crayon? Pastel? Or a water colour paint? Silk Crayons go on silky smooth like a pastel (the colours are more vivid that a standard wax crayon) and then to change the look you simply add water with a paintbrush to create a water colour effect. Silk Crayons are non-toxic, odour free and water-soluble so stains are easily washed out. The extra fun bit is each crayon comes in a twist-up tube (just like mum’s lipstick), so there’s no mess and no waste. Suitable from 3
