Zera Annex Oyster is an 1" x 6" matte porcelain mosaic from Anatolia Tile. Visually it offers a matte face that absorbs light rather than bouncing it. A stacked format gives the wall or floor a pattern of its own. On the residential side that covers kitchens, entry halls and main-floor living areas. One box contains 10 pieces, enough for 9.58 sq ft. Porcelain is pressed and fired dense enough that it takes water and traffic a wall-grade ceramic would not. Made in Malaysia.
