As far as I know, no pens are allowed. Only HB 2 pencils and the stylus/tablet pen they provide. It's confusing cause earlier (right before the digital arrived), pens were the requirement I believe.

On the website if you click "What am I allowed with me during the LSAT-Flex" it specifically states No.2 pencils or HB pencils. Says nothing about pens.
Hey! Mechanical pencils are not allowed for the LSAT Flex, only NR.2 or HB. I didn't run into any problems. My proctor did ask to see my pencils and both sides of my 5 pages of scratch paper.
I am now ready to score a 220 on the Jan lsat, get a letter of rec from Michelle Obama, and consequently, earn a $1mill scholarship to Harvard Law. Impossible is nothing. In the words of Charlie Sanders, "Kids, You can literally fly.."
