We purchased 5 boxes of the black Trentie wall tiles. We had to sort through all 200 tiles as many were scratched due to there being no paper between each tile. We had 2 usable boxes of tiles and took the others back to the store. The first Male assistant told us they are cheap and you get what you pay for! Thank goodness for Jill, who he delegated the job of finding 120 usable tiles to. And she missed her break because of it. We discovered all the boxes had the same problem and finished up removing the first 2 tiles from each box as they were the best. Yes I know they aren’t the most expensive tiles but they still have to be fit for purpose by law. I suggest B&Q remove all the black ones from sale immediately, so no-one else loses a whole afternoon sorting through them. P.S. I bought them because I like them, not because they are cheap. They’re a nice looking tile poorly packaged.
