Economical. Slate can be brittle so I was not surprised to have some breakage in my initial order. Wayfair was very helpful and shipped the replacement tiles promptly. There is a variety of color and texture. I find the quality to be a cut above the slate available at big box stores but not as nice as the tiles Ive hand selected at specialty tile shops. I suggest that you just order a little bit more than the minimum for your project.
