    Durable & Beautiful
  

*by I***M on Reviewed in the United States on April 15, 2024*

I purchased these to ship outgrown clothing items from my kids closets on another website. (not allowed to use the name) The mailers are a good weight and resist punctures with a strong side seam. They are a great size and will fit most clothing items.I waited until I had used them a while to write a review. I have had no damaged packages from the100 items shipped. The last brand I used, I had to toss more than 50 of them after 4 damaged shipments. I wish these were biodegradable like that other brand, but those just weren't durable. The color is beautiful and really makes my package stand out. I have received high ratings for packaging from buyers.  I will definitely purchase these again and can definitely recommend them to other shoppers.

    These are AWESOME
  

*by M***S on Reviewed in the United States on August 23, 2024*

We use these to ship our Ebay orders in.  The sticky is really sticky and I really do not have to reinforce them very often unless I accidentally make a mistake.Work as intended, hold up really well.
