Handcrafted finishing created by De Castelli for indoor use only. The characteristic color of this material is due to the long exposition of copper outside. De Castelli accelerates this process in order to offer a product with a mature oxidation. Once stabilized, it is 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. Indoor use only. 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. Samples images are an indication only and do not replace the use of real ones, since it is not possible to guarantee a reproduction identical to the original.
