These tiles aren't 12x12. While the sticker itself is, the tiles themselves are really 12x10, as they overlap. While I enjoy the overlap feature for install, that extra two inches stacks up, and I found that even though I ordered more than I needed, "just in case", I'm going to potentially have to order more, which makes me angry. It's still a good price for the product; they really could have just listed the correct dimensions and I'd be very pleased with this purchase. As it stands, however, I have a half-finished backsplash and an attitude adjustment to make.
