## Questions & Answers

**Q: Where are these made?**
A: US of A

**Q: What packaging do the poly mailers come in?**
A: Stack of 100 bags is folded and placed inside another poly mailer by the manufacturer. Method is secured enough that manufacture also included in each bag (FREE of charge) a sheet of “HANDLE WITH CARE” labels.

**Q: What mil thickness are these.**
A: There's no info on the bags themselves but they're about the same thickness and rigidity as another bag I have that claims to be 2.4 mil so I'd say they're in that 2-2.4 ballpark

**Q: is there a bag with one clear outer surface?**
A: They may have some that are clear on one side but these are not.

Nice thick quality poly mailers. These are a great size to ship out sweatshirts. Seals great and I am not worried about them getting torn in the mail.

### ⭐⭐⭐⭐⭐ Reliable and Durable – Perfect for Small Business Shipping
*by G***E on July 30, 2025*

This is my second time purchasing these poly mailers, and they continue to impress. We use them for our small business shipping, and they hold up extremely well — even when packing boxes with sharp edges. Unlike other mailers we’ve tried that are too thin and tear easily, these are sturdy, well-made, and the self-sealing adhesive is strong and secure. Great quality and value for the quantity. Highly recommend for any business looking for dependable shipping supplies.
