Amos Colorix Silky Twisters Crayons are a vivid, water-based crayon featuring a convenient plastic body that protects the crayon and keeps hands clean. The crayon stick extends by twisting the knob at the base of the pen, making it easy to use up to the last bit. The crayons are smooth-writing and can be used like normal crayons, blended together like pastels, or used with a water-brush to create a watercolor effect. This set contains 12 colours: Blue, Black, Brown, Coral Orange, Green, Light Green, Orange, Pink, Red, Sky Blue, Violet, and Yellow.
