Dutch colorists and pencil crafters, Bruynzeel, have been producing the finest artist grade pencils since the 1940's. Crafted with care and attention to detail, these colored pencils are double glued all the way down the core and the casing to ensure that even if the wide gauge core breaks, it does not fall out of the casing.The liquid wax binder ensures the purest pigmentation, and the best blendability without creating a wax bloom. The finest light cedar casing allows for excellent sharpening and the finely ground and highly lightfast pigments allow for a subtle, smooth and consistent color release.
