    Perfect

Just sturdy enough to not need a bubble mailer

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    A bit flimsy, but price is right
  

*by N***. on Reviewed in the United States on August 28, 2024*

A little bit flimsy, compared to slightly smaller size, and the tape strip works just okay.  I have to put another piece of heavy cardboard in with the document, to help keep item from getting damaged in the mail.  The price is right, and I will keep coping with them, as the next grade up is just crazy expensive.
