Primrose is based on an art nouveau tile design Nawal Motawi discovered in a book. Motawi Tile's desinger, Nawal, experimented with many iterations before arriving at this pared-down version with an Arts and Crafts vibe. Motawi tiles are made with a custom mix of clays and pressed from original plaster molds. Every tile is hand-glazed and embossed on the back for authenticity. At approximately 5/8 inches thick, every tile has a notch in the back for hanging unframed. Made in the USA. To clean, wipe with a damp cloth using mild soap. Ceramic. Measure 4 x 8 in.
