These were easy to use and printed well on my laser printer. The printing was close to the edge of the card and I had to manually move each line as the margin setting didn’t work well.
I assumed these would be cardstock weight. They're not. I don't think I could use these for mailing unless I put them in an envelope. They're good for other stuff though. I have an etsy shop and they're good for thank you card inserts. That's just not why I bought them.
