Durable shipping poly mailers!
Very durable poly mailers for shipping products. I’ve used several hundred of these and never had an issue. No issues with unsealing during shipping of products. The color is a nice deep blue.

They literally do exactly what the description says. Shipping was fast, and the mailers didn’t rip even though they are lightweight

These are pretty good. A little more flimsy than I would like so probably wouldn’t buy them again.
