Polished Light Grey Molding Trim Tile.
There were some mixed reviews so I was hesitant in using wholetiles but I'm so glad I did. There selection is great, being able to buy sample pieces really helped in making it easy and inexpensive to actually see the pieces and coloring before I bought them in bulk. Not one single piece was damaged or broken and anytime I had a question they responded very promptly. I would definitely recommend them and will be using them in the future.
