I searched for ages for a black and white morroccan style tile for my bathroom floors that wasn't astronomically expensive and shipped relatively quickly. These were perfect! My previously pink/orange tiled bathroom is now so clean and classy. The black is not a very dark black- it's more like a very dark charcoal grey. The tiles are matte and not slippery, and look good with dark grey grout. 

My only complaint would be that I wish they sold boxes with fewer tiles (or individual tiles). I only really needed 1 box, but to have a few extra just in case I had to purchase a second box.
