## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great packaging
  

*by A***E on Reviewed in the United States on 21 February 2021*

These are great! I use them to send fragile license plate frames. My clients receive them unharmed. I just have anxiety about the closure and add a sticker for extra security, even though it probably doesn’t need it

### ⭐⭐⭐⭐⭐
