### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect for mailing cards/prints
  

*by A***R on Reviewed in the United States on November 29, 2023*

There are a lot of "rigid" mailers out there but these are very thick and very sturdy. If you are mailing cards or other paper products, these are going to give you the best chance of no bending from the mail people. I have also ordered the cheaper ones but they are flimsy and require you to add a cardboard insert anyway so it ends up coming out to the same price as these sturdier ones. These also look more professional, if you are using for business.

    my favorite rigid mailers!
  

*by A***Y on Reviewed in the United States on July 4, 2023*

my favorite rigid mailers, great quality and super reasonably priced. i've purchased this several times now over many other brands and these are just the right amount of thickness/weight (not too flimsy, but not so heavyweight that it throws your oz over the threshold and sturdy enough to keep your flat prints etc intact)some reviews mention the adhesive which to be fair does require some hard pressing. but if you're using 4x6 labels you can just attach them to the opening side and press them over the seal for security--and voila! no extra tape needed.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great quality mailers for a decent price!
  

*by D***E on Reviewed in the United States on August 30, 2023*

These mailers are perfect for shipping my Amazon Handmade Greeting Cards.  The 6 by 8 inches is perfect for my 5x7 cards.  There is just enough room for the cards and a plastic protective sleeve.  They are as sturdy as the mailers used by a well known printing company.  They shouldn't bend in transport.  I shopped around a lot and you can't beat these for quality and price.  I highly recommend these mailers.
