I’ve purchased these a few times as I use them for shipping thrifted clothes. They are the perfect size and I feel like the material is pretty heavy duty. They never tear. The seal sticks really well. I’ve never had any complaints with shipping in these polymailers and I’ve shipped hundreds of items with them!

I use these to ship items that I sell on eBay. They work great for mailing out clothing, papers, or other such items. I love how easy and inexpensive they are to use.

These poly mailers are fantastic! The 10x13 size is perfect for small businesses, and the self-sealing feature saves time. The black color looks sleek and professional. Durable, lightweight, and great value for 100 pieces. Highly recommend for secure shipping. A must-have for eCommerce sellers!

Quality product at a great price will be buying more!

I purchased these bags for selling items sold online. I thought the size would great for USPS. What I found was they are too small for most items. You really need to be able to buy bags that can fold and seal. They work fine if you are mailing thin things like media items or perhaps tax returns, children's books that are thin, maybe a shirt. I went with longer and wider bags can be folded based on what is being shipped and easily handles shipping labels. Once folded the shipping cost under a pound for USPS Ground Advantage is under $5 anywhere in the USA.

Got these for depop and i’m so glad i did, buying bags separately adds up and buying a bunch is so much more cost efficient. All bags were in perfect condition, they are strong and durable i’m very glad i got these!

Great Product Will Definitely Buy from them Again
