As well as being color coded these cutting boards have icons in the corners that are designated to certain foods.
Red - meat
Green - fruits and vegetables
Yellow - poultry
Blue - fish
The material used for these flexible cutting boards is US-made, FDA approved virgin food grade plastic, using Microban® technology to ensure that odor causing bacteria is killed even before it has the chance to contaminate the plastic cutting board set. Safe for the family, it is BPA free and dishwasher safe.
As with some other cutting boards these will NOT dull your knives. You can easily use them as a funnel and store flat in a drawer.
A great hands on review for HomeWarez's flexible cutting boards.
