Mailers
A little thin compared to some mailers. But they work just fine!

great quality
We ship out approx. 30 orders a day that we use these bags for and we have never had a complaint yet from a customer saying that the package was opened because the adhesive wasn't sticky enough. We have gone through a couple thousand of these bags.

You get what you pay for
These are thin and cheap feeling compared to other mailers I’ve used. However, I have shipped out several of these with clothing, and haven’t had a single complaint. They are lightweight and don’t add much to shipping costs. They aren’t as nice as others, but if you’re looking to keep your overhead low, this is a good option.

DO NOT BUY — terrible quality
These are the worst quality polymailers uber seems. I’ve ordered 20,000+ polymailers from different sellers and I’ve never seen something this bad. They are almost see through thin, they have a terrible smell, the edges are all ripped. Do not purchase
