What type of icons are being used on this page of the enfold demo page

hi on the enfold demo page

http://kriesi.at/themes/enfold/homepage/transparent-header/

When we scroll down under the immediate slider there are 4 columns and one is free support, one mobile ready etc

I’m trying to recreate this. How do I?

I did try icon, icon list and icon box but i dont think its any of them. Please advise

Thank you
