Silk crayons is a fun set of eight vibrant colouring-in pens for children.

• Silk crayons go on silky smooth like a pastel, but you can change the look by simply adding water with a paintbrush, to create a water colour effect. Colours are brighter than normal wax crayons.
• Silk crayons are non-toxic, odour free and water-soluble so stains can be easily washed out.
• The extra fun bit is that each crayon comes in a twist-up tube, so there is no mess and no waste.
