### ⭐⭐⭐⭐⭐ 







  
  
    Perfect for mailing art!
  

*by J***Y on Reviewed in the United States on June 10, 2020*

I use these to mail my etsy art and they are perfect.  Sturdy and keep contents safe!  I do include a "do not bend" sticker but I have not had any issues with it bending!  Good size too, I can fit a cardboard page protector, cellophane page protector, 1-6 pictures, several cards, and stickers all in one package. I use it to mail 8.5x11 inch pages, but you can fit 9x12 pictures in them too.

### ⭐⭐⭐⭐⭐ 







  
  
    Great for shipping paintings

### ⭐⭐⭐⭐⭐ 







  
  
    Great quality
  

*by D***D on Reviewed in the United States on December 13, 2018*

I used to buy similar envelopes from Uline, but no longer need large quantities. It's great to buy great quality envelopes in  such small quantities via Amazon with Prime 2-day delivery, to boot. Life is good!
