Super smooth gel crayons with easy-grip twistable end mean no peeling or sharpening required. Washable and non-toxic, which makes them great for use with younger children. The washable feature means that they are watersoluble and can be blended with water and a brush when first applied to the canvas or paper, or could be rubbed with fingers. This accentuates how versatile they are across age groups and projects. Smooth Moves Crayons hold their intensity of colour once they dry. Individual unit size: 18mm diameter, 130mm length.
