Handcraft finishing created by De Castelli for indoor and outdoor use. Brushed copper is obtained manually with Scotch-Brite, than protected with a transparent varnish. Differences compared to the sample provided are not to be considered as a manufacturing defect, but as a feature of the manual processing, that may be susceptible to variances in color and homogeneity. If placed outside, the finishes can experience dissimilar color alteration, which should not be considered faults. For cleaning and maintenance only use a cotton cloth dampened with water or specific neutral products for varnished surfaces. Do not use abrasive cloths, solvents, alcohol or strong detergents. Dry the surface thoroughly in case of standing water.
