Koru Mink is a 24" x 24" porcelain tile with rectified edges, which allows a tighter grout joint. The face carries the movement of quarried stone. A glaze is fired onto the body, which is what carries the colour and pattern. A PEI 4 rating suits heavy residential and light commercial floors. It is frost resistant, so it can run from an interior floor onto a covered porch or patio. A box holds 4 pieces and covers 15.24 square feet. Made in Spain.
