These non-traditional cutting boards have a heck of a lot going for them. Unlike glass they will not dull your cutlery, unlike wood they will not absorb odors or bacteria. Theyre durable, dishwasher and oven safe, you can even use them as warming trays in the microwave. The upturned rims prevent spills and overflows onto your counter and they even have a measuring guide, so you can be as precise as possible when it matters.
