Colour-Coded Fleximats 5 "So very useful." Mrs Worth 01 July 2018 I have used these Fleximats for years and find them indispensable. As the name suggests they really are flexible, much nicer than copies I have seen on sale elsewhere. They can be used to prepare food on, to funnel liquids or dry goods into jars, cut to specific sizes, and a few dozen other uses. Dishwasher safe too. I wouldn't be without them.
