    Did the job, but feel a little short on expectations.

We ship out lots of items and love using poly bags when possible to help save on shipping weight. These bags are great for doing just that. They do seem to be thinner then advertised or made of less quality poly. We were surprised when they showed up with a matt finish instead of the shiny poly bags that we had gotten from other vendors. These did do their job, however we probably wouldn't buy the matt finish poly bags again. They just seemed a little off.

These are a little thinner than other poly mailers I have used and a few have torn.
