Great for shipping art prints
I use these to ship fine art prints and they are perfect. I love how ridged they are, nice clean white packaging to add my own branding to. Adhesive holds well. Seem durable. I do add a piece of cardboard in with each print for additional rigidity.

Works perfectly for my mailing
My coffee table book fits perfectly in the mailer. The material seems sturdy enough... how the books arrive at their destinations remains to be seen. If I get any complaints, I will update this review. I remain hopeful.

Perfect for my needs
These hold my 310 page 6”x9” books perfectly and give good protection. So far I haven’t had one book damaged after hundreds of orders. The adhesion is very strong too. Great product and price.

The perfect size to add rigidity to USPS priority mail flat rate envelopes
This is a really good size to add rigidity to usps flat rate envelopes without adding much extra thickness and still allowing for a seamless close. No matter what you use them for they are a great quality mailer.

Not self-sealing
I really like the weight of these for shipping prints and calendars. I add a "please do not bend" sticker to the packaging for the postal workers. Overall a good product, and I bought 2 sizes: 9x12 and 13 x15. On the 13x15, the adhesive strips work fine. The adhesive strip does NOT work at all on the 9x12 size. Not even for a moment. I seal with packing tape. I bought 700+ of these for my online store and am not excited to add the extra step of having to seal each one.
