Mailers Shipping Mailing Envelopes Bags by MoTffice Poly Mailer Envelopes Bags 5 Mil Thick White 10.24x13.4 inch Waterproof Opaque Anti-Stretch Tear-Resistant Mail Bag 50pcs

These sleeves do a great job of protecting the contents. They are thick and durable and the adhesive strip is as strong. I was surprised about the quality considering the price. Worth the purchase.

I used these to trade-in some books to Amazon and to return jeans. They were a good size. The only negative was that one did tear, but I just used packing tape to cover it up. I would buy them again as they were easy to use making my life simple - always a win!

I purchased these for mailing things and not having to add additional postage. They are durable, and I have yet to get a complaint from someone on the other end saying their product was damaged. When dealing with the USPS, that speaks for itself.

Just what I was looking for! Thin material but seems sturdy enough for my shipping needs. No complaints.

I found the products to be exceptionally well for my shipping purposes. The thickness as well as the adhesive worked perfectly.

These envelops are a little thin but they do the job.

Great staple item in my home as we order many items on line and some times have to return things.

These bags have a very good adhesive strip which holds very well.
