Selm: Wow! I'll check that out, thanks!
Tessagin: I'm not sure what the brand is, I'm not home right now to inspect it in person, but I asked my son to look at it and he says there is no apparent branding on it. I bought it at JoAnn's a while back. After purchasing it and noticing that my blades dulled more quickly on it than on my Olfa mats, I read (here, I think) that others were having similar issues with "white mats." The mat is very "plasticky" compared to green mats and is not self-healing, as far as I can tell.
