||The Castle Brick Series offers five colors with beautiful variety. A coordinating corner piece provides increased flexibility for design applications. Because this material is a porcelain product, minimal maintenance is required. There can be noticeable variances between pieces, so it is important and recommended that a range of this product be viewed before finalizing a purchase. Piece to piece variation in shade or color are inherent in all fire clay products; therefore it is recommended to mix tiles from several boxes at a time during installation to achieve the best range of color.
