Vex Starstruck Rules

Hi all,
I am fairly new to using vex anti-slip mats, but I have been doing vex for 2 years now. I looked on the vex manual about using them and how much but it wasn’t even on there. It just talks about non-vex parts and etc that are unrelated. So could someone clarify if anti-slip mats are allowed to be used on our robot and if so, how much of it? Thanks! I was thinking of making a wall bot this year just for kicks.

You may use as much of it on your robot as you like

Anti-slip mat is an official vex component. Therefore, you can use as much as you want.
