I had been buying HP brochure paper for my business' brochures when suddenly the brochure paper got VERY flimsy and wouldn't remain standing in the holders. Staple's card stock not only takes the place of the HP brochure paper that is no longer what it used to be but does a better job.
I used the card stock to print figures for the use as visuals in classes and to make art projects and they worked well. The only negative thing was that the sheets didn't fold well but I have used for many others purposes and it is great.
