### ⭐⭐⭐⭐⭐ 







  
  
    Great for postcards (1st class postage needed)
  

*by K***G on Reviewed in the United States on July 14, 2020*

Being stuck at home during a pandemic for months, we're starting to run out of things to entertain ourselves, so I got the kids into making mail art... Looking for an affordable and sturdy substrate, these fit the bill wonderfully. They are thick enough to support collaging, pen and ink, and paints without warping significantly, and at 5x7" they are mailable as first class mail in postcard format (or buy some envelopes to go with them). I did not try them in the laser printer, as I think they would be too thick to hold toner well, but inkjet also works great. They are very thick and quality paper, and the cuts are precision-made. I did not try them in the laser printer, as I think they would be too thick to hold toner well, but inkjet also works great. Only complaint is a handful had their corners smashed a little, but since these are going in the mail as postcards that didn't matter to us. Definitely recommend for mail-related projects.

    Cards were cut crooked
  

*by D***K on Reviewed in the United States on July 14, 2020*

The thickness and quality of this card stock is great.  However, two sides were cut crooked.  Meaning that when I fed them into the printer, the prints came out crooked.  I now have to cut each piece myself down. Since I had to slice the sides, they are no longer actually 5x7 and I've had to fix my graphics accordingly.

### ⭐⭐ 







  
  
    Poorly Packaged - Damaged upon receiving
  

*by K***K on Reviewed in the United States on August 24, 2021*

These papers are actually great, super thick and sturdy.The only issue is how poorly they are packaged, with absolutely no protection at all.I received mine with the wrapper already broken open, and papers loose in the mailer.Sadly I will be returning them.
