New platter mat larger than OEM. Safe to use?

I bought a new platter mat. (First pic) but it’s about 1-2mm thinner and about 5mm larger in diameter than the original. It’s made of silicone. In the second pic I’ve put my original mat on top so you can see the size difference. The third pic is trying to show the overhang. I’d say it’s probably around 2mm?

Is this ok to use or should I return it?

Thanks!
