## Questions & Answers

**Q: How much does each mailer weigh?**
A: Not more than 2 oz.  They vary slightly by style and material.

**Q: How much US postage/stamps will this require?**
A: The USPS does NOT count this as a small parcel. It qualifies as a letter because its shortest side is between 3.5" and 6.125", its longest side between 5" and 11.5", and its thickness is between .007" and .25". When filled, as long as this mailer remains under .25" in thickness and under 3.5oz in weight, its rigidity does NOT bump it up to large envelope/flat or even parcel, but instead incurs a non-machinable surcharge. Under current prices, one should be able to send this mailer anywhere in the continental US for $.88 – $1.30.

**Q: Will a flat item fit inside that is exactly 8" in length?**
A: Good morning! Just barely. and it has to be pretty much flat. But I measured it, and the fold is a hair under 8 inches. hope this helps.

**Q: How thick is the envelope? gsm? is it a heavyweight paper?**
A: VERY thick. I don't know what gsm stands for but they are "hard" almost.

### ⭐⭐⭐⭐⭐ *Slaps Envelope*
*by T***E on November 2, 2022*

This bad boy can fit so much freaking mail in it! I have bought, rebought and re rebought these mailers so many times, I should've bought and rebought stock in the company by now... I sell and ship stickers and these work great for keeping everything safe. They're durable enough to keep the enclosed items flat but not so heavy duty that they weigh too much. and They're the perfect size for the printed shipping labels that I use. Been shipping with these for a few years now and have never had a single one of them get damaged during shipping. They're WAY more dependable than my ex! The seal is good too, almost tooooo good... Yeah don't accidently seal them up before you finish putting everything inside that needs to go inside cause once it's closed, it stay that way, there is no reopening it and resealing it. Long story short 10 outa 10 would buy again and again and again and again and again and again. Make sure you smash that like and subscri... Oh wait this is Amazon. Hope you enjoy the review and found it helpful! Don't forget to love each other! - Witty
