3 Non-Slip Fleximats 5 "I love these" Mrs Dewdney 14 February 2017 I bought these as my work top is shiny black and thought the black one would "stay" in the main area but that did not suit me. I use the beige one every day when at home, the white one I keep in my suitcase for when we travel, being well used at the moment! dont have a problem with slipping just make sure underneath is dry. Washing it I put in sink a dash of suds and a scrub with the washingup brush. Yes it gets scored with the knife but what doesn't. Love the way you can lift and take it to the bin. Will be buying a second set on my next order thought you had stopped selling them.
