This is nice thick card stock that does not bleed through. I used these for invitations and printed a full color picture on front, black & white print with a color image inside and a color image on the back. They looked fantastic! Of course I did need to keep the pages separated for a minute, so the ink could dry, but nothing smeared and they looked fabulous. The only trouble I had was that I couldn't find an option for this Avery size in my Word 7, so I used what I thought was closest to that size and it worked just fine (and that is why I didn't give it 5 stars). I would definitely purchase these again!
