Best In Test Chopping Mat 5 "BEST IN TEST CHOPPING MAT" Mrs Lam 10 May 2019 It IS... undoubtedly. I have had one for over a year, and there is NOT A MARK on it, and it is in use every day. WONDERFUL! Unlike some of the beautiful ones where you have a separate one for every type of thing.. which are ornaments. ( You know the ones I mean?) The first thing you cut will mark them. Not fit for purpose. The Best in Test IS. I shall never ever buy anything else.
