With the perforations these cards provide a great way to send messages to multiple individuals. I format a 4-part box in Microsoft Word to create the content. Very practical ! !
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.
