Model Building Protective 'Surface'

Question from a novice…

I’ve seen many YouTube model reviews with the kit parts placed on a protective table covering about 30" x 24" that has inscribed and/or painted-on measured squares. It resembles the large paper cutters one saw in art class at school, only without the cutting mechanism. Appears to be a very hard, scratch-resistant surface.

What is that thing called? (Would like to purchase one.)

Are you referring to a cutting mat?

Thanks!

That gives rise to a new product someone should put on the market. I use Contact paper or similar product to cover the surface of my bench top. I use plain white now. It would be great if someone would do an adhesive backed shelf lining material with a nice grid printed on it!
