American Olean Refined Metals Hammered Bronze Metal Tile (Satin).
This tile is normally very expensive, I've seen it anywhere from 500-600 dollars a box (retail).
28 pieces in a box. Each piece is 4x8. Each piece is .2178 square feet. There are 6.09 square feet in each box. If you need a few extra pieces past whatever quantity of boxes you need to buy, let me know and I'll toss them in for free. If you need an extra half a box, you'll have to buy two boxes.
