They did a good job at stacking the tiles in the box so that as you take them out to lay side by side they fit together well. I did however still leave a gap between some tile so that I could fill in with loose stone I previously broke off to ensure there was no distinct line between each tile piece. It is so comfortable to walk on and I couldnt be happier with the color. Picture was taken with flash on so you can really see the colors but it overall it is a nice dark shade.
