quick translation of the terms of usage:
buying this resource you'll acquire the rights to use it anywhere you want with no restriction whatsoever (in comics, illustrations, graphics, ads, personal stuff....) via internet or printing or whatever support you need to. So, if you want to use one of my textures as a background for a comic and then get it published and sold in shops: that's great!
What you CAN'T do is redistribute and re-sell the files themselves. I need to eat too guys.
