Water-resistant, non-toxic pencils that layer and blend beautifully without a waxy buildup. The 3.8mm lead diameter contains special oils and binder that allows the pencils to create dense, even strokes without the use of heavy pressure. The broad edge is excellent for shading, while the finely sharpened point creates exquisite detail. The leads are encased in California Cedar for easy sharpening. The 12-color set includes yellow, orange yellow, vermilion, carmine, violet, light blue, dark blue, grass green, dark green, Indian red, brown and black.
