I purchased these for my granddaughter for Christmas, so they have no been used, however I did check out the quality.
These are right on par with the construction paper you get at big box stores. Sturdy and a thick mil. Excellent for craft projects to keep the littles busy over the cold winter months. I got her a set of glitter markers to go with this, they're going to show up beautifully on this.
Don't just save them for the kids, thse are excellent if you love art. Oil painting, water color, and as odd as it might sound, even a pencil drawing would look beautiful on this. They are the standard 8.5x11, so will fit in the basic frames for display. Excellent choice!
