Durable and roomy
Purchased these to mail t-shirts. These were perfect. Large enough to hold multiple shirts, pliable so I was less concerned about the package getting hung up in mail machines, and durable so I was not concerned about rips or other damage. Highly recommend if mailing cloth items.

I can't really rate this other than size, which is perfect for storing my legal documents in. My safe creates moisture over a period of time (a natural condition of this unit per the owners manual) and I've never seen a ziplock bag that size, so this was my choice. I folded the excess down and used packing tape to seal the sides. We'll see!

The packing tape was on sale and it's always good to have for holiday boxes being mailed.

Perfect for my use
I do art and sometimes mail matted watercolor paintings to friends and relatives. The various envelope sizes are perfect for the various sizes of paintings. I cut a piece of cardboard sized to the painting and they always arrive in good condition.

12"W x 15.5"L Self Seal Poly Mailer, 5/Pack
Worked for what I needed. Price was $5.99 at the store where I purchased, but were on sale at $2.99. I would never pay the full price. Only bought these because the brown clasped envelopes I needed were out of stock.

Great way to mail packages
Mailing product in these poly bags is so much easier than finding the right size shipping box. You can pack them more fully and take advantage of all the soft space. Plus no extra weight to the package when its time to ship them. And best of all you can tuck them away in a drawer, no storing shipping boxes in closets any longer.

Fragile but Tough
While packing something for mail out, a slight pull and the sealing portion came off in my hand. Other than that light weight and tough enough for the mail.

Cut down the side
Make sure you check them good before you purchase. Every single one of them were cut down the side. Like a razor blade or box cutter. I had to tape one up just to mail.
