Bendy Boards are a great idea, combining the flexibility of thin chopping mats with the knife-friendliness of thicker poly prep boards. Bendy Board sets contains two 11.5" x 14.5" boards, each 2 mm thick. Bendy Boards are easy to curl up, so you can funnel chopped onions into a pan or bowl, but they're thick enough to cushion fine knife edges from the unyielding kitchen counter under the board. Made in Sweden. Dishwasher safe.
