Once you are over the 2kg Eparcel weight you start looking for things to fill the 5kg void. Perfect little "box filler" wish they had bigger ones but this has many handy rulers and geometric references all over it on both sides. It's not too thick and made of very dense material so you won't be cutting through this baby easiely at all.
Even better than expected. This cutting mat is very thick (approx 3mm) AND has cutting surface printed on BOTH SIDES. The reverse side is pretty much a straight line grid for sizing stock, but it isn't described in the product listing so it was a complete surprise. BARGAIN!!!!
