I've had my Kai mat for over 30 years and it still looks brand new.
It's a different material than the self-healing mats. It's thinner but a little stiffer, and it's far more durable. There are no indents or grooves from the rotary cutter like with other mats. Seriously, this thing still looks almost brand new.
I also been using the same Kai rotary cutter all these years, and they have phenomenal scissors. I'm a big fan of this Japanese brand.
