Don't use them, we bought a house lot of floor tiles and we got 15m2 less than we paid for. They gave us plenty of excuses "they must have been stolen from the house site.. the tiler must have broken them.." They ripped us off and when we confronted they were abusive and threatening. The bloke strutted around like he wanted a fight and the chick was just plain nasty. Do yourself a favour and stay away from this lot!
