Review: Top Notch quality! - Bought these KKBESTPACK 14.5x19 Poly Mailers and wow—these bags are TOUGH. Like, “package survives a wrestling match with the mail carrier” tough. The material is strong, and the adhesive? Once you seal it, that package is sealed for life. No turning back. No regrets.

For a pack of 100, this is an amazing value—my wallet is happy and my packages are safe. Will I order again? Absolutely. These mailers and I are in a long-term relationship now. 💌📦

## 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.
