Pebblz Grey Sink Mat Regular 4 "Loving my new mat" 05 April 2016 I've used a different version for the past few years, which finally needed replacing. The grey version looks better in the sink than the clear, strangely. Yes it does stain very easily, but most comes off in the dishwasher, or soaking in a bit of bleach, or even a bit of lemon juice can clean it straight up. It fits perfectly in the sink and I love that some pebbles are smooth and some are grippy to make it very non-slip. The edges of the pebbles are beveled so when the water hits them they don't spray water everywhere. A very good product.
