Indention here means that the rings that the domes make(the red rings from pressure) can be seen even after hours,days of using NB..They are not red and not VERY obvious in most cases but they are like a shadow of the place where the domes where..Like a mark or something..Sometimes they are white and sometimes a little bit darker than the skin color.I hope i explained that somehow well.If you still didn't get it let me know.Maybe will find a better way of expalining it
