The Arches line of Watercolor Brushes is synonymous with quality and elegance. Along with the finest Kolinsky red sable and grey squirrel hair, each brush features longer, more balanced, ergonomic handles. Handles are made from matte varnished blond oak or richly grained African hardwood. All brushes in the Arches line feature nickel plated anodized brass seamless ferrules with sgraffito tip. The Arches innovative cap is a marvel of functionality and elegance. Its transparent qualities allow the artist to see the hair type, and being that the cap is rigid and jointed it can be used again and again. Easy to put on and remove: it opens and closes with a click, no risk of damaging the hair. Ventilated for full drying of the hairs. In four sizes to fit series A1, A2 and A4.
