At this price actually unbeatable. The format is A2, the edges are rounded and not sharp. So you will not cling to it which could possibly disturb while working. The grid on the product photo is also to find on the supplied mat and helps with 1cm or 5cm 5cm grid and grid square roughly gauge the size and also to set times without ruler brands!
I cut a lot with Cutter, utility knife and bow with quite coarse grit. The cutting mat "swallows" cuts easily and thus support a clear straight cut, because unlike a stone, glass or a hard surface can here the blade penetrate easily and pushes the blade not to the side, which would have crooked cuts result!
Of course, this also protects your precious tables. ;)
By and large a good purchase, I can unhesitatingly recommend it!
